Question & Answer :
I’m utilizing minute.js to format my day clip, present I person 2 day values, and I privation to accomplish a peculiar relation once 1 day is larger than the another. I publication about of their docs, however didn’t discovery the relation to accomplish this. I cognize it volition beryllium location.

This is my codification:

var date_time = 2013-03-24 + 'T' + 10:15:20:12 + 'Z' var d = minute(date_time).tz('UTC'); // archetypal day var present = fresh Day(), dnow = minute(present).tz('UTC'), snowfall = dnow.infinitesimal() % 15, diffnow = 15 - snowfall, tonow = minute(dnow).adhd('infinitesimal', diffnow), ahead30now = minute(tonow).adhd('infinitesimal', 30); if (d > ahead30now) { // let enter clip console.log('UTC Clip DB', d.format()); } other { }

Edit

var date_time = req.assemblage.day + 'T' + req.assemblage.clip + req.assemblage.timezone; // 2014-03-24T01:15:000 var utc_input_time = minute(date_time).utc(); // 2014-03-24T01:15:000 console.log('utc transformed date_time', minute(date_time).utc().format("YYYY-MM-DDTHH:mm:SSS")); var isafter = minute(utc_input_time).isAfter(minute('2014-03-24T01:14:000')); // actual if(isafter === actual){ console.log('is last actual'); } other { console.log('is last is mendacious'); }

Present, I americium evaluating 2 dates i.e. 2014-03-24T01:15:000 > 2014-03-24T01:14:000, anticipating that the archetypal 1 is higher than the 2nd 1, however it ever goes to the other information. I don’t cognize wherefore?

I accept you are wanting for the question features, isBefore, isSame, and isAfter.

However it’s a spot hard to archer precisely what you’re trying. Possibly you are conscionable wanting to acquire the quality betwixt the enter clip and the actual clip? If truthful, see the quality relation, diff. For illustration:

minute().diff(date_time, 'minutes')

A fewer another issues:

  • Location’s an mistake successful the archetypal formation:

    var date_time = 2013-03-24 + 'T' + 10:15:20:12 + 'Z'

    That’s not going to activity. I deliberation you meant:

    var date_time = '2013-03-24' + 'T' + '10:15:20:12' + 'Z';

    Of class, you mightiness arsenic fine:

    var date_time = '2013-03-24T10:15:20:12Z';

  • You’re utilizing: .tz('UTC') incorrectly. .tz belongs to minute-timezone. You don’t demand to usage that until you’re running with another clip zones, similar America/Los_Angeles.

    If you privation to parse a worth arsenic UTC, past usage:

    minute.utc(theStringToParse)

    Oregon, if you privation to parse a section worth and person it to UTC, past usage:

    minute(theStringToParse).utc()

    Oregon possibly you don’t demand it astatine each. Conscionable due to the fact that the enter worth is successful UTC, doesn’t average you person to activity successful UTC passim your relation.

  • You look to beryllium getting the “present” case by minute(fresh Day()). You tin alternatively conscionable usage minute().

Up to date

Based mostly connected your edit, I deliberation you tin conscionable bash this:

var date_time = req.assemblage.day + 'T' + req.assemblage.clip + 'Z'; var isafter = minute(date_time).isAfter('2014-03-24T01:14:00Z');

Oregon, if you would similar to guarantee that your fields are validated to beryllium successful the accurate format:

var m = minute.utc(req.assemblage.day + ' ' + req.assemblage.clip, "YYYY-MM-DD HH:mm:ss"); var isvalid = m.isValid(); var isafter = m.isAfter('2014-03-24T01:14:00Z');
