How do I pass date in RFC2822 format, to an URL in GET method:
e.g I want to pass 18th jan 2013 as min_date_created in the URL https://www.xyz.com/orders
18th jan 2013 in RFC format is ==> Fri, 18 Jan 2013 17:58:49 +0000
how can I pass it to URL?
TIA!
Instead of passing the date as a string, you could convert it to the number of milliseconds since midnight Jan 1, 1970:
var time = new Date('Fri, 18 Jan 2013 17:58:49 +0000').getTime(); // 1358531929000
widow.location.href = 'https://www.xyz.com/orders?min_date_created='+time;
This way you won't have encoding problems.
Or you could also use encodeURIComponent(), see URL encode sees “&” (ampersand) as “&” HTML entity

I'm trying to parse this date Wed, 17 Feb 2021 13:00:00 +0100 into this 2021-02-17 13:00:00.000000000 +0100.
And I've tried using this Time.strptime(current_time.to_s, '%Q'), (where current_time it's the date above) but I get 1970-01-01 01:00:02.021 +0100
But I don't understand why I get another date, could you help me? Thanks!

You seem to already have an instance of Time: (or ActiveSupport::TimeWithZone which is Rails' drop-in replacement with better timezone support)
current_time = Time.current
#=> Thu, 19 May 2022 10:09:58.702560000 CEST +02:00
In this case, there's nothing to parse. You just have to format it via strftime the way you like:
current_time.strftime('%F %T.%N %z')
#=> "2022-05-19 10:09:58.702560000 +0200"
Parsing is only needed when you have a string representation that you want to turn into a Time object, e.g.: (using Rails' Time.zone.parse variant)
time_string = 'Thu, 19 May 2022 10:09:58.702560000 CEST +02:00'
time_obj = Time.zone.parse(time_string)
#=> Thu, 19 May 2022 10:09:58.702560000 CEST +02:00
time_obj.class
#=> ActiveSupport::TimeWithZone
When using the format-date function on a date formatted like "Fri, 10 May 2019 01:15:00 GMT", I get an error: Invalid date "Fri, 10 May 2019 01:15:00 GMT" (Non-numeric year component)
I would like to obtain a dd/MM/yyyy format .
If you use XSLT 2 chances are you use a processor like Saxon 9 or AltovaXML which have since 2017 (e.g. Saxon in release 9.8 or later or Altova in releas 2017 or later) updated to support XSLT 3 and XPath 3.1 where you could then make use of the parse-ietf-date function (https://www.w3.org/TR/xpath-functions/#func-parse-ietf-date) to parse your input string into a xs:dateTime on which you could then apply the format-dateTime function:
format-dateTime(parse-ietf-date('Fri, 10 May 2019 01:15:00 GMT'), '[D01]/[M01]/[Y0001]')
https://xqueryfiddle.liberty-development.net/6qM2e2m/1
Your current approach doesn't work as the format-date function works on xs:date and not on arbitrary formatted date strings. That particular format you have shown in your sample can be parsed by the parse-ietf-date function.
I'm trying to parse a specific hour of a specific date. When I put the date directly as an argument, it works fine, but when I create a variable and put it in the argument it returns the current date.
Why is that?
NOTE: the variable time is 9pm and I need to parse 9pm of 12 March 2016.
datetime = DateTime.new(2016,3,12,9)
=> Sat, 12 Mar 2016 09:00:00 +0000
DateTime.parse("sat 12 march 2016 9pm")
=> Sat, 12 Mar 2016 21:00:00 +0000
DateTime.parse("datetime 9pm")
=> Mon, 14 Mar 2016 21:00:00 +0000
In your third call, you use the literal string "datetime" rather than the value of your datetime variable. You can use string interpolation to use the variable's value:
DateTime.parse("#{datetime} 9pm")
In this case, the "9pm" is ignored since it doesn't make sense added to the end of an existing date but this is why the initial attempt wasn't working. Interpolation is generally a solution for using a variable's value rather than its name.
If your goal is to change the time of an existing date, use the change method:
datetime.change(hour:21)
You can also try this
date = Date.new(2016,3,12)
DateTime.parse("#{date} 9pm")
## Output
Sat, 12 Mar 2016 21:00:00 +0000
OR
datetime = DateTime.new(2016,3,12,9)
DateTime.parse((datetime + 12.hours).to_s)
## Output
Sat, 12 Mar 2016 21:00:00 +0000
OR
DateTime.parse((datetime + 12.hours).to_s).strftime("%a, %d %b %Y %I:%M %p")
## Output
Sat, 12 Mar 2016 09:00 PM
I know it is common error but I could not resolve it even after trying those answers.
Through the rest api I am sending some parameters inculdes dates. I am recieving all the data in the method where I want but when I am trying to parse Date it throws error of invalid date.
Here are my parameters that I am recieving
{"uid"=>"1", "user"=>"abc.a#abc.com", "from"=>"Mon Nov 3 24:59:12 CET 2014", "to"=>"Tue Nov 11 24:59:12 CET 2014"}
and Date format is
Mon Nov 3 24:59:12 CET 2014
but it is throwing error on parsing on line below
fr = DateTime.parse(params[:from]) unless params[:from].empty?
I tried strptime as well but did not work.
Imp points is I need hour also for later processing. Thanks
what you are doing wrong is parsing DateTime while it is just date and should be parsed as one of the following ways:
1.
>> fr = params[:from].to_date unless params[:from].empty?
=> Mon, 03 Nov 2014
2.
>> fr = Date.parse(params[:from]) unless params[:from].empty?
=> Mon, 03 Nov 2014
You have 24:59 which is invalid time. Anyway, use strptime:
DateTime.strptime("Mon Nov 3 22:59:12 CET 2014", "%a %b %e %T %Z %Y")
#=> Mon, 03 Nov 2014 22:59:12 +0100
The user inputs a date range let's say from yesterday with any timezone.
from_datetime = "10/01/2012 00:00 +0545"
I get purchased time for the book like below:
purchased_at = Book.where("created_at > #{from_date}").purchased_at
=> Fri, 08 Jun 2012 09:44:26 UTC +00:00
The problem is this gives me UTC time but I want to show the purchased_at time in the requested time_zone which can vary.
I can't use in_time_zone as the input from_date only has time offset, can I ?
purchased_at.in_time_zone("Kathmandu")
=> Fri, 08 Jun 2012 15:29:26 NPT +05:45
Is there any way around?
Give an offset, you can get a timezone name from ActiveSupport::TimeZone:
> ActiveSupport::TimeZone[5.hours + 45.minutes]
=> (GMT+05:45) Kathmandu
Then you can hand that to in_time_zone:
> Time.now.in_time_zone(ActiveSupport::TimeZone[5.hours + 45.minutes])
=> Thu, 18 Oct 2012 12:33:12 NPT +05:45
You can pull the offset out of the from_datetime with a bit of simple wrangling if you know the incoming format.
There are issues with this approach:
The mapping from offset to name isn't unique.
DST could be a problem if ActiveSupport::TimeZone[] gives you the wrong name.
Depending on your needs, you could just apply the offset manually and ignore the timezone when formatting the timestamp:
> (Time.now.utc + 5.hours + 45.minutes).strftime('%Y-%m-%d %H:%M:%S +0545')
=> "2012-10-18 12:40:12 +0545"
