i'm trying to calculate the difference between two UTC Datetime Strings with angular-momentjs like shown below:
var start = "1970-01-01T11:03:00.000Z";
var end = "1970-01-01T11:15:00.000Z";
var duration = $moment.utc($moment(end).diff($moment(start))).format("hh:mm");
when i execute the code above, the duration should be 00:12 but actually it is 12:12. I don't understand why and how to fix it.
You are actually creating a moment.js object for 1970-01-01T00:12:00.000Z, then getting the time as hour and minutes. The token "hh" is for 12 hour time, so you're seeing "12" for 12am. If you want to see 00:12, use the token "HH" which gives 24 hour time: 00:12.

So I have the following script:
import groovy.time.TimeCategory
def dueDate = context.expand( '${Test 4 - create user task#Response#$[\'_embedded\'][\'userTaskDtoList\'][0][\'dueDate\']}' )
def date = new Date(messageExchange.getTimestamp())
use(groovy.time.TimeCategory){
after24Hours = (date + 24.hours).format("yyyy-MM-dd'T'HH:mm:ss'Z'", TimeZone.getTimeZone('UTC')) }
assert dueDate == after24Hours
What I'm trying to do with this is take the date and time from a REST request (dueDate - which comes in UTC format and with a 24h delay) and create a new date and time from the timestamp of the moment when that request has been sent, which is registered from my system. I then convert that time to UTC to accommodate the format from dueDate and add 24h to it. At the end I verify that the date and time from dueDate and after24Hours is the same.
The output does return the same time but in certain cases if there is a delay between the time the request is being sent and the time is received then the assertion will fail. This depends on the server, usually there is a difference of like 1 millisecond but I'm thinking that if the server will be slower at some point this will definitely be bigger.
What could I do to allow some margin of error in the assertion, maybe like a few seconds or even a couple of minutes?
Ok, so I managed to do this:
import groovy.time.*
def dueDate = context.expand( '${Test 4 - create user task#Response#$[\'_embedded\'][\'userTaskDtoList\'][0][\'dueDate\']}' )
def date = new Date(messageExchange.getTimestamp())
use(groovy.time.TimeCategory){
after24Hours = (date + 24.hours).format("yyyy-MM-dd'T'HH:mm:ss'Z'", TimeZone.getTimeZone('UTC'))
def date1 = Date.parse("yyyy-MM-dd'T'HH:mm:ss'Z'", dueDate)
def date2 = Date.parse("yyyy-MM-dd'T'HH:mm:ss'Z'", after24Hours)
TimeDuration difference = TimeCategory.minus(date2, date1)
log.info date1
log.info date2
assert difference < 2.minutes
}
The script seems to work and it does return an error only if the time is longer than the one I've set in the assertion.
Unfortunately I have another issue now.
For some reason, my date output looks like this:
Fri Oct 01 16:24:10 EEST 2021: INFO: Sat Oct 02 13:24:10 EEST 2021
Which is not the correct format. That date should appear in the Zulu format, after all when I parsed the dates that was the format that I used.
Am I missing something?

Instead of asserting that they are equal, you could assert that the difference between them is less than a threshold that you get to define.
If you use something like AssertJ, and I'd recommend you do, then you can do something like the following:
assertThat(dueDate).isCloseTo(after24Hours, within(1, ChronoUnit.MINUTE));
This will give a small margin to the comparison of the dates, and should fix your issue.
I'm confused.
I have a textbox that is populated with a date and time (string) such as '09/07/2021 10:30'.
I convert this string to a moment like so:
var suggestedDateObj = moment(suggestedDate, 'DD/MM/YYYY HH:mm');
I then want to check if this date and time is in between time slots in a fullcalendar.js event object. I do this like so:
var startDateObj = moment(value.start);
var endDateObj = moment(value.end);
if (suggestedDateObj.isBetween(startDateObj, endDateObj)) {}
However...it isn't working. And it's due to timezone offset (i think).
suggestedDateObj returns a value with a UTC offset of +0100 (British Summer Time)
However my calendar event objects return a date with a UTC offset of +0000. So when i check if '09/07/2021 10:30 +0100' is in between '09/07/2021 10:30 +0000' and '09/07/2021 11:30 +0000' it doesn't work!
I guess my question is really either:
How can I create my suggestedDateObj moment with a timezone offset of zero? OR
How can i tell fullcallendar events that the time it is displaying is actually BST (+0100)? At the moment I don't specify the 'Timezone' parameter.
Thanks.
UPDATE
Hmm....this might work....although it feels a bit clunky:
var tmoment1 = moment(suggestedDate, 'DD/MM/YYYY HH:mm');
//create default date with specific timezone offset of zero
var suggestedDateObj = moment().utcOffset(0);
//set the date and time
suggestedDateObj.set({
day: tmoment1.day(),
month: tmoment1.month(),
year: tmoment1.year(),
hour: tmoment1.hour(),
minute: tmoment1.minute(),
second: 0
});
You can generate suggestedDateObj in utc like that:
var suggestedDateObj = moment.utc(suggestedDate, 'DD/MM/YYYY HH:mm');`
For the .isBetween() I suggest you to use the square bracket like forth parameter, like documentation says.
if (suggestedDateObj.isBetween(startDateObj, endDateObj, undefined, '[]'))
The square brackets indicate that the check must include the dates of the limiter
I am trying to calculate the number of days between two dates using moment js.
function (value) {
var expiration= moment(value).format('DDMMYYYY');
var today = moment().format('DDMMYYYY');
var dayToExpiration = moment(expiration- today).format('D[days] ,H[hours]');
console.log(today + " : " + expiration
console.log(dayToExpiration);
The result is:
11102018 : 28102020 //--> 11.10.2018 : 28.10.2018
1 days ,6 hours //why only one day??
Because your dayToExpiration variable should be a moment.Duration object, not a string.
The difference between two datetimes is a duration, not a datetime.
Short answer:
As John Madhavan-Reese stated in his answer, you have to use moment Duration to represent the diffecence between two moments in time.
Issue in the code sample:
In your code you are creating a moment object from the difference between expiration and today. This value is interpreded by moment as the number of milliseconds since the Unix Epoch (see moment(Number)), so you are creating a moment object for a random day around the 1st January 1970 (see the output of moment(expiration- today).format() ). The D token in format() stands for Day of Month, so it gives an "incorrect" output.
My suggested solution:
You can calculate difference using momentjs' diff() then you can create a duration using moment.duration(Number).
Finally you can get your desired output using moment-duration-format plug-in (by John Madhavan-Reese :D)
Here a live sample:
function getDiff(value) {
var expiration= moment(value); // Parse input as momement object
var today = moment(); // get now value (includes current time)
// Calculate diff, create a duration and format it
var dayToExpiration = moment.duration(Math.abs(today.diff(expiration))).format('D[days], H[hours]');
console.log(today.format('DDMMYYYY') + " : " + expiration.format('DDMMYYYY'));
console.log(dayToExpiration);
}
getDiff('2018-10-28');

I am getting errors. this one works for me:
moment.duration(expiration.diff(today))._milliseconds / (1000*60*60*24));
How do I add minutes to this. I followed the documentation but somehow this is not working:
var hours = randomIntFromInterval(0,23);
var minutes = randomIntFromInterval(0,59);
var time = moment(hours+':'+minutes,'HHmm').format("HH:mm");
time.add(7,'m');
Only the last line is not working, but should be right according to the documentation. What am I doing wrong?
format returns a string, you have to use add on moment object.
Your code could be like the following:
var hours = randomIntFromInterval(0,23);
var minutes = randomIntFromInterval(0,59);
var time = moment(hours+':'+minutes,'HH:mm');
time.add(7,'m');
console.log(time.format("HH:mm"));
Note that you can create a moment object using moment(Object) method instead of parsing a string, in your case:
moment({hours: hours, minutes: minutes});
As the docs says:
Omitted units default to 0 or the current date, month, and year
You can use IF condition to see if minutes < 10
to add "0" like 07,08
var d = new Date()
var n = d.getMinutes()
if(n<10)
n="0"+n;
But watch out you will have to slice that zero if you want to increment.
I'm trying to get the difference in minutes between two timestamps
I have a timestamp that looks like this to begin with
'15:44:06'
And when I want to find the time elapsed I create a new moment timestamp
var currentTimestamp = Moment(new Date()).format('HH:mm:ss');
Which returns this
'15:42:09'
I then attempt to get the difference like so
var duration = Moment.duration(Moment(currentTimestamp,'HH:mm:ss').diff(Moment(userTimestamp,'HH:mm:ss')));
And then attempt to get it in minutes
var elapsedTime = duration().asMinutes();
console.log(elapsedTime);
But in the console when I log it I get this error
var elapsedTime = duration().asMinutes();
^
TypeError: object is not a function
I got most of this code from this stackoverflow
You can get the diff by using the moment constructor properly.
First, when you initialize your time stamp, you should use the following format:
var timestamp = moment('15:44:06','HH:mm:ss');
Second, when you want to use the diff function with the current time you should user it like so:
timestamp.diff(moment());
Then, the given number can be converted to minutes with .asMinutes() (the first )
for further information you should read the official docs here.
You can also try this with the lastest moment.js
var start = moment('15:44:06','HH:mm:ss');
var minutesPassed = moment().diff(start, 'minutes');
This question is getting a little bit old, this answer just bring the state up to date with a solution the question was looking for:
const startDate = moment();
...
elapsedDuration = moment.duration(moment().diff(startDate));
//in minutes
elapseDuration.asMinutes();
As per documentation about diff
and display duration in minutes
