I have a form on which I set a start Date and a finish Date for a entity.
On the Web Api side, before saving the date to the database,I set the start date: 2013-09-25 00:00:00.000 and the the end date as 2013-09-26 23:59:59.000.
var vote = (VotingSet)Entity;
vote.Start = new DateTime(vote.Start.Year, vote.Start.Month, vote.Start.Day, 0, 0, 0, 0);
vote.End = new DateTime(vote.End.Year, vote.End.Month, vote.End.Day, 23, 59, 58);
This is from the JSON that is send to the rest service looks like this:
Start: "2013-09-25T00:00:00.000Z"
End: "2013-09-26T00:00:00.000Z"
After the save, in the javascript client, the entity is updated with the new key and with the properties that come from the server.
The observable date objects will have the following value
Start: Wed Sep 25 2013 03:00:00 GMT+0300 (GTB Daylight Time)
End: Fri Sep 27 2013 02:59:58 GMT+0300 (GTB Daylight Time)
This is what i am getting back from the server
Start: "2013-09-25T00:00:00.000"
End: "2013-09-26T23:59:58.000"
How can i make sure that the hours in my object are not modified?
EDIT:
There is a a good explaniation here on what's happening with the datetime in javascript.
In the end i used this snipped to solve my problem:
breeze.DataType.parseDateFromServer = function (source) {
var date = moment(source);
return date.toDate();
};
It override's breeze own function with adds a time offset to the datetime.
Breeze does not manipulate the datetimes going to and from the server in any way EXCEPT to add a UTZ timezone specifier to any dates returned from the server that do not already have one. This is only done because different browsers interpret dates without a timezone specifier differently and we want consistency between browsers.
This is discussed in more detail in the answer posted here.
You are passing ISO8601 formatted timestamps, which is good. When you pass the Z at the end, you are indicating that the timestamp represents UTC. When you load those into JavaScript, it's going to take that into account.
You still need to show more code if you are looking for a useful response. What you've currently described from .NET doesn't quite line up with the timestamps you've provided. And it seems like most of this problem has to do with JavaScript and you haven't yet shown any of that code, so I can only guess what you might be doing. Please update your question, and understand that we have no knowledge of your system other than what you show us.
It's possible you may find moment.js to be useful in this scenario, but I can't elaborate further without seeing the relevent JavaScript code.

In the MySQL DB: '2020-04-19 22:00:00'(UTC). That's also what my endpoint returns since I set the connection option dataStrings:true.
On the client, after I fetch date:
const timezone = moment.tz.guess();
const convertedDate = moment(date)
.tz(timezone)
.format();
convertedDate then equals to "2020-04-19T22:00:00+02:00" (I'm in the UTC+2 zone).
I would like to get it in the format "2020-04-20T00:00:00" instead. How can I do that?
It looks like moment(date) believes your incoming date value is in local time, not UTC. So, your timezone conversion to local time changes nothing. You can tell moment it's UTC, like this:
const timezone = moment.tz.guess();
const convertedDate = moment.utc(date)
.tz(timezone)
.format();
You do not need moment-timezone for this. With Moment by itself you can use the utc function when parsing, and the local function to convert to the user's local time zone before formatting.
moment.utc('2020-04-19 22:00:00').local().format()
//=> "2020-04-20T00:00:00+02:00"
Also, the Moment team recommends using Moment for existing projects only. For new development, we recommend using Luxon instead:
luxon.DateTime.fromSQL('2020-04-19 22:00:00', {zone: 'utc'}).toLocal().toISO()
//=> "2020-04-20T00:00:00.000+02:00"
It's a rails project. I have a form where the user can schedule tasks. For the moment I get the timezone of the browser with :
var currentTime = new Date();
var timezone_offset = currentTime.getTimezoneOffset()
And then I use it in my controller. But the problem is :
How can I save the date to be scheduled to the right moment?
I thought the answer will be to parse the date from my form and then change the offset but it doesn't work:
> time = Time.parse("2015/11/30 12:00")
=> 2015-11-30 12:00:00 +0100
> time.change(offset: '+02:00')
=> 2015-11-30 12:00:00 +0100
Maybe the answer is to create a Time.new?
My heroku server is on UTC. Some users on CET.
You would be better off getting your form to submit the time in UTC format.
Using something like moment.js (http://momentjs.com/) you can get their local time in the browser and display the date/time in their local format, but submit the UTC counterpart to the server when submitting your form.
One of my co-workers has written an application in Grails 2.4.4 (I know, it's dated). One problem the app has is that you can enter a date like 2/31/2015 and it will be accepted as valid and will show up in your domain object as 3/3/2015 instead.
Is there any easy way to prevent this from happening using grails? Or do we instead have to rely on client side validation for this particular property?
Thanks.
Assuming that Grails is using DateFormat to parse the date String, the issue is that it's using a lenient Calendar. For example, with lenient set to true (the default), the result is as you described:
import java.text.SimpleDateFormat
def sdf = new SimpleDateFormat('MM/dd/y')
assert sdf.parse('02/31/2015').toString() == 'Tue Mar 03 00:00:00 EST 2015'
But, if you change it to false, you'll get an exception for the same date:
sdf.lenient = false
try {
sdf.parse('02/31/2015').toString() == 'Tue Mar 03 00:00:00 EST 2015'
} catch (java.text.ParseException ex) {
// java.text.ParseException: Unparseable date: "02/31/2015"
println 'Oops'
}
So to handle this validation in your controller, you can
Create a command object.
Have the command object accept the date as a String rather than a Date, and perform the date validation.
Modify the controller action to use the command object instead of params. This may require modifying the GSP code as well.
I am trying to get the timezone from native calendar using the following code but i am getting the timezone has Asia/Calcutta instead of just 'IST'
Calendar calendarLocal = Calendar.getInstance();
// fetches time zone
TimeZone timeZone = calendarLocal.getTimeZone();
System.out.println("Time Zone getAvailableIDs() --->"+timeZone.getAvailableIDs());
String[] x=timeZone.getAvailableIDs();
for(int i=0;i<x.length;i++){
System.out.println("Time Zone IDs-->"+x[i]);
}
System.out.println("Time Zone ID--->"+timeZone.getID());
System.out.println(" Calender Default-------->>>"+timeZone.getDefault());
System.out.println("Time Zone --->"+timeZone.getTimeZone(timeZone.getID()));
Here TimeZone is Asia/Calcutta i need it to print IST
BlackBerry Java doesn't give you the time zone short codes, at least not reliably (it only gaurantees to know about the "GMT" code). You can see my answer here for information about how to code a mapping between strings like "Asia/Calcutta" and "IST". (my method mapTimeZoneCodes() in that example)
I provide a template method for setting up the mapping, and a link to this article on Desktop Java, which seems to have a pretty complete list of the time zone codes, and how to map codes to the long Java time zone strings.
It will be boring work to copy the strings into my template, but once you have it, you'll be able to easily lookup the short code based on the long name:
String longName = timeZone.toString();
String shortCode = (String)_timeZones.get(longName);
Summary
We are experiencing a problem where the systemDateGet() function is returning the
AOS wher the local date is required when determining the date for posting purposes.
Details
We have branches around the world, both sides of the international date line, with
users connecting to local terminal servers with the appropriate time zone settings
for the user's branch.
Each branch is associated with a different company, which has been configured with
the correct time zone.
We run a single AOS with the time zone setting set for the head office. There is
not an option to introduce additional AOS's.
The SystemDateGet() function is returning the AOS date as the user is not changing
their Axapta session date.
A number of system fields in the database related to posting dates are DATE based and
not UTCDATETIME based.
We are running AX2009 SP1 RU7.
Kernel version 5.0.1500.4570
Application version 5.0.1500.4570
Localization version: Brazil, China, Japan, Thailand, India
I am aware that the SystemDateGet() function was designed to return the AOS date unless
the user changes their session date in which case that date is returned.
Each user has the appropriate time zone setting in there user profile.
Problem
One example of the problem is when a user attempts to post a journal involving financial
transactions, where the ledger period is checked to see if it is open. For example,
the user is in England attempting to post a journal at 3:00pm on the 30st of November, local
time, the standard Axapta code uses the systemDateGet() function to determine the date to use
in the validation (determining if the period is open). In our case, the AOS is based in
Brisbane Australia and the systemDateGet() function is returning the 1st of December
(local time 1:00am on the 1st of December).
Another example of the problem is where an invoice is posted in the United States on a Friday
and the day of the week where the AOS is situated is a Saturday. We need the system to
record the local date.
Question
Besides rewriting all system code involving systemDateGet(), over 2000 entities, is there
any other options that can be used to get around the problem of getting the correct local
date?
Solution limitations.
In the example given above of the ledger period being closed, it is not possible from a
business practices standpoint to open the next period before end of month processing
has been completed.
There is currently no option for the purchase of additional AOS's.
Create a function in the Global class:
static date systemDateGetLocal()
{
return DateTimeUtil::date(DateTimeUtil::applyTimeZoneOffset(DateTimeUtil::utcNow(), DateTimeUtil::getUserPreferredTimeZone()));
}
Then in Info.watchDog() do a:
systemDateSet(systemDateGetLocal());
This may only be a partial solution, the watchDog is executed on the client side only.
Here is a quick update. Let me know if there are any issues or situations that need to be addressed.
USING LOCAL TIME
Introduction:
The following is a work in progress update, as the solution has yet to be fully tested in all situations.
Problem:
If the user has a different time zone to the AOS, the timeNow() and systemDateGet() functions are returning the AOS details when the local date time is required.
Clarifiers:
When the local date time is changed within Axapta, the systemDateGet() function will return the local date, however the timeNow() function still returns the AOS time.
Coding changes:
A number of coding changes have been made to handle a number of different situations. Comments will be added where an explanation may be required.
The brackets were changed to { and } to allow this to be posted.
CLASS:GLOBAL
One requirement I was given was to allow the system to handle multiple sites within a company that may have different time zones. Presently this functionality is not required.
static server void setSessionDateTime(
inventSiteId inventSiteId = '',
utcDateTime reference = dateTimeUtil::utcNow())
{
str sql;
sqlStatementExecutePermission perm;
connection conn = new UserConnection();
timeZone timeZone;
int ret;
;
if (inventSiteId)
{
timeZone = inventSite::find(inventSiteId).Timezone;
}
else
{
timeZone = dateTimeUtil::getCompanyTimeZone();
}
//This is to get around the kernel validation of changing timezones
//when the user has more than one session open.
sql = strfmt("Update userInfo set preferredTimeZone = %1 where userInfo.id = '%2'", enum2int(timeZone), curUserId());
perm = new SQLStatementExecutePermission(sql);
perm.assert();
ret = conn.createStatement().executeUpdate(sql);
dateTimeUtil::setUserPreferredTimeZone(timeZone);
dateTimeUtil::setSystemDateTime(reference);
CodeAccessPermission::revertAssert();
}
static int localTime()
{
utcDateTime tmp;
;
setSessionDateTime();
tmp = dateTimeUtil::applyTimeZoneOffset( dateTimeUtil::utcNow(), dateTimeUtil::getCompanyTimeZone());
return dateTimeUtil::time(tmp);
}
The following method was implemented as a cross check to ensure that systemDateGet() returns the expected value.
static date localDate()
{
utcDateTime tmp;
;
setSessionDateTime();
tmp = dateTimeUtil::applyTimeZoneOffset( dateTimeUtil::utcNow(), dateTimeUtil::getCompanyTimeZone());
return dateTimeUtil::date(tmp);
}
CLASS:APPLICATION
Modify the method setDefaultCompany. Add the line setSessionDateTime(); directly after the super call. This is to allow the time to change when the user changes company (another requirement I was given).
CLASS:INFO
So that the system uses the correct date/time from the start of the session.
void startupPost()
{
;
setSessionDateTime();
}
Modify the method canViewAlertInbox() adding the line setSessionDateTime(); as the first line. This is to handle if the user has multiple forms open for different companies.
Localization dependent changes:
Depending on your service pack and localizations, you will need to change a function of objects to use the localTime() function, replacing timeNow(). IMPORTANT NOTE: Do not change the class BatchRun to use the new localTime function as this will stop it working correctly.
In our system there were around 260 instances that could be changed. If you do not use all modules and localizations the actual number of lines you need to change will be less.
Final note:
There are a number of today() calls in the code. I have not yet gone through each line to ensure it is coded correctly, i.e. using today() instead of systemDateGet().
Known issues:
I have come across a situation where the timezone change function did not work completely as expected. This was when one session was doing a database synchronisation and another session was opened in a different company. As normal users will never be able to do this, I have not spent much time on its solution at this stage. It is something I do intend to resolve.
