NSDate timeIntervalSince1970 not working in Swift? [duplicate]
(3 answers)
Closed 6 years ago.
I am trying to convert milliseconds to date string in swift 3,i tried by setting date fomatter but i am not getting current date string.
var milliseconds=1477593000000
let date = NSDate(timeIntervalSince1970: TimeInterval(milliseconds))
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy HH:mm:ss"
formatter.locale = NSLocale(localeIdentifier: "en_US") as Locale!
print(formatter.string(from: date as Date))
output:
22-01-48793 01:30:00
Try this,
var date = Date(timeIntervalSince1970: (1477593000000 / 1000.0))
print("date - \(date)")
You will get output as date :
date - 2016-10-27 18:30:00 +0000
How about trying this -
let milisecond = 1479714427
let dateVar = Date.init(timeIntervalSinceNow: TimeInterval(milisecond)/1000)
var dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy hh:mm"
print(dateFormatter.string(from: dateVar))
Have a look at the documentation of NSDate:
convenience init(timeIntervalSince1970 secs: TimeInterval)
Returns an NSDate object initialized relative to the current date and time by a given number of seconds.
Just convert your milliseconds to seconds and you should get the correct date.

How can I parse / create a date time stamp formatted with fractional seconds UTC timezone (ISO 8601, RFC 3339) in Swift?

I have a date as String but I want to convert it to Date.
The date in string looks like this - "2022-09-09T07:00:00.0000000".
Code to convert it to Date:
public static func dateStringToDate(dateString: String) -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale.autoupdatingCurrent
dateFormatter.timeZone = TimeZone.current
dateFormatter.setLocalizedDateFormatFromTemplate("MM-dd-yyyy HH:mm:ss")
return dateFormatter.date(from: dateString)
}
No matter what I do, I keep getting nil as the output. I tried with ISO8601 template as well and got nil. I commented out line "setLocalizedDateFormatFromTemplate" but still got nil. Can't figure out what am I missing or doing wrong in the code.
First of all, this is an excellent resource. I think what you are looking for is this:
func dateStringToDate(dateString: String) -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSS"
return dateFormatter.date(from: dateString)
}
dateStringToDate(dateString: "2022-09-09T07:00:00.0000000")

You have the year, then month, then day, then hour, minute, second, fractional seconds
Use this Snippet of code
func dateStringToDate(dateString: String) -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale.autoupdatingCurrent
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSSSS"
return dateFormatter.date(from: dateString)
}
You were not providing the proper date format

I am struggling quite a bit with dates. I have the following code:
Current Date in Amsterdam: 22-Februari-2022 - 11:40
Current Date in New York: 22-Februari-2022 - 05:40
The dateBoughtString goes in as follows: 2022-02-18T19:50:47.081Z
The current date is just the current date.
let dateFormatterNew = DateFormatter()
dateFormatterNew.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
dateFormatterNew.timeZone = TimeZone(abbreviation: "GMT+1:00")
dateFormatterNew.locale = Locale(identifier: "nl-NL")
let dateBoughtTemp = dateFormatterNew.date(from: positionStatsString[0])!
print(dateBoughtTemp) // Prints: 2022-02-18 18:50:47 +0000
dateFormatterNew.timeZone = TimeZone(abbreviation: "GMT-5:00")
dateFormatterNew.locale = Locale(identifier: "en_US")
let dateNowTemp = dateFormatterNew.string(from: Date())
let dateBoughtTempTwo = dateFormatterNew.string(from: dateBoughtTemp)
print(dateNowTemp) // Prints: 2022-02-22T05:41:49.973Z
print(dateBoughtTempTwo) // Prints: 2022-02-18T13:50:47.081Z
let dateNow = dateFormatterNew.date(from: dateNowTemp)
let dateBought = dateFormatterNew.date(from: dateBoughtTempTwo)
print(dateNow!) // Prints: 2022-02-22 10:41:49 +0000 **INCORRECT**
print(dateBought!) // Prints: 2022-02-18 18:50:47 +0000 **INCORRECT**
When I convert to string all seems fine and it works as it should.
But when I convert those strings back to a date they just go back to Amsterdam time with the current date even being one hour off.
What am I missing here?
The problem is in your's parameter 'Z':
'' means that it's content doesn't involved in time formatting.
So when you apply timeZone parameter date is printed in particular time zone without correct timeZone suffix and when it's scanned it's scanned in particular time zone, just expecting that there will by Z character at the end. So when you are formatting to date and then to string you are accumulating error caused by timezone difference.
Correct format will be "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" or better to use ISO8601DateFormatter because you can't set invalid format in it.
So your printed dates will have valid timezone suffix and timezone suffix will be considered in backward conversion.
Another moment: you shouldn't convert string back to date with localized formatter, if it's UI part, but for that you can use UIDatePicker instead of UITextField.
So full code will be:
let isoDateFormatter = ISO8601DateFormatter()
isoDateFormatter.formatOptions = [.withInternetDateTime, .withFractionalSeconds]
let date = isoDateFormatter.date(from: "2022-02-18T19:50:47.081Z")!
let now = Date()
do {
let amsterdamDateFormatter = DateFormatter()
amsterdamDateFormatter.timeZone = .init(abbreviation: "GMT+1:00")
amsterdamDateFormatter.dateStyle = .long
amsterdamDateFormatter.timeStyle = .short
print("now in Amsterdam: \(amsterdamDateFormatter.string(from: now))")
print("time in Amsterdam: \(amsterdamDateFormatter.string(from: date))")
}
do {
let newYourkDateFormatter = DateFormatter()
newYourkDateFormatter.timeZone = .init(abbreviation: "GMT-5:00")
newYourkDateFormatter.dateStyle = .long
newYourkDateFormatter.timeStyle = .short
print("now in NY: \(newYourkDateFormatter.string(from: now))")
print("time in NY: \(newYourkDateFormatter.string(from: date))")
}
Use the below code for formatter, Change the timezone and dateFormat according to your need:
let formatter = DateFormatter()
formatter.calendar = Calendar(identifier: .iso8601)
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.timeZone = TimeZone(secondsFromGMT: 0)
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSXXXXX"

Swift ISO8601 format to Date returning fatal error

I think this is an ISO8601 formatted timestamp.
2021-07-05T22:26:51.159Z
I'm trying to convert it with ISO8601DateFormatter() in swift 5.
Here's what I've tried:
let dateFormatter = ISO8601DateFormatter()
dateFormatter.formatOptions = .withFullDate
//ISO8601DateFormatter().formatOptions = .withFractionalSeconds
let d = "2021-07-05T22:26:51.159Z"
let date = dateFormatter.date(from: d)
The result:
date = 2021-07-05 00:00:00 UTC
The day is correct, the time is not. I've tried to set the .withFractionalSeconds option. Didn't help.
How should I convert this format?
You can use standard date formatter to achieve this:
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ"
let date = dateFormatter.date(from: d)
print(date)

I am converting current date into GMT/UTC date string. But every time it returns me with wrong date.
My todays date is 07 February 2020, 11:09:20 AM. You can refer below image.
Here is my code :
let apiFormatter = DateFormatter()
//apiFormatter.dateStyle = DateFormatter.Style.long
//apiFormatter.timeStyle = DateFormatter.Style.long
//apiFormatter.calendar = Calendar.current
apiFormatter.timeZone = TimeZone.init(identifier: "GMT") //TimeZone(abbreviation: "UTC") //TimeZone.current //
//apiFormatter.locale = Locale.current
//apiFormatter.dateFormat = "yyyy-MM-DD HH:mm:ss"
apiFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
//apiFormatter.dateFormat = "yyyy-MM-dd'T'hh:mm:ssZ"
let endDate = apiFormatter.string(from: Date())
print(endDate)
And what I am getting in return is also you can check in image - 2020-02-38T05:33:34.598Z. I have tried with all the format, but no any luck. Can anyone suggest where it is going wrong?
First of all, the format should be:
apiFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
The Z is not a literal letter, it's the description of the time zone. However, making it a literal won't probably make a problem.
The 38 for day from your output is obviously caused by the DD format you have commented out.
Nevertheless, you have to set the locale:
apiFormatter.locale = Locale(identifier: "en_US_POSIX")
Otherwise you will have problems with 12/24h switching.
let apiFormatter = DateFormatter()
apiFormatter.locale = Locale(identifier: "en_US_POSIX")
// remove this if you want to keep your current timezone (shouldn't really matter, the time is the same)
apiFormatter.timeZone = TimeZone(secondsFromGMT: 0)
apiFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let endDate = apiFormatter.string(from: Date())
print(endDate) // 2020-02-07T08:25:23.470+0000
print(Date()) // 2020-02-07 08:25:23 +0000
Also note that you can use ISO8601DateFormatter instead of DateFormatter.
Try this and adjust according to what format you are getting from server -
private func getFormatedDateInString(_ dateString: String) -> String? {
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
dateFormatter.timeZone = TimeZone(identifier: "UTC")
if let date = dateFormatter.date(from: dateString) {
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
dateFormatter.timeZone = TimeZone.current
let timeStamp = dateFormatter.string(from: date)
return timeStamp
}
return nil
}

I'm formatting a date string to date object using below code. But for some date strings it works and for some it returns nil.
Format = "yyyy-MM-dd'T'HH:mm:ss.sssZ"
"2019-04-02T09:47:24.055Z" Works
"2019-03-27T22:31:17.140Z" Doesn't work
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.sssZ"
let date = dateFormatter.date(from: "2019-03-27T22:31:17.140Z")
Your format is wrong. It should be:
"yyyy-MM-dd'T'HH:mm:ss.SSSZ"
Have a look at date time format here:
https://unicode.org/reports/tr35/tr35-dates.html#Date_Format_Patterns
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = dateFormatter.date(from: "2019-04-02T09:47:24.055Z")
let date1 = dateFormatter.date(from: "2019-03-27T22:31:17.140Z")
print(">>>>>!!", date, date1)
Optional(2019-04-02 09:47:24 +0000) Optional(2019-03-27 22:31:17 +0000)
The code above works as expected.
use SSS instead of sss
for your case of
yyyy-MM-dd'T'HH:mm:ss.sssZ and 2019-04-02T09:47:24.055Z
output was :
Optional(2019-04-02 09:47:55 +0000) nil
look at minutes and seconds:)
