Doubt with moment.js

Navigation
1

I have a question about the use of moment.js, the question is, if today I put a date and time for example 03/14/2018 at 01:00, I usually keep the UTC time in the database to then format it to the date / time that corresponds depending on the region of the client (hence the use of moment), so far, but I have a problem, which is, instead of being today, for example I put it in August (that there is a different schedule) because I do not see the time well, until you have that kind of schedule, change from +1 to +2 hours depending on the time of year.

So my question is, if I want to set a date time, for example 08/14/2018 at 1, I want to see the 1, be it in March or August, but I do not understand very well how to do this .

I hope any help, thanks.

The problem is that when doing the format with moment it takes as default the timezone of the United States, then it changes the schedule. To avoid that, it's a matter of changing the moment.js timezone by adding the moment-timezone library.

For example: 

moment.tz("2014-06-01 12:00", "Europe/London");
// Europe/London: 2014-06-01T12:00:00-04:00
moment.tz("2014-06-01 12:00", "America/New_York");
// America/New_York: 2014-06-01T17:00:00+01:00

I do not know how you do the time change utc to local time but this is done with the time zone , I do not know if moment.js does this internally because it does not I've used it but you can always do it yourself with the javascript date object: 

var d = new Date();
var n = d.getTimezoneOffset(); // te entrega el offset en minutos (+2 = 120)

Now the timezone knows when the time change is, if you ask the offset on August 13 at 23:59 it will tell you for example +1 (60) and if you do it on August 14 at 00:00 will tell you +2 (120).

I hope this serves you, greetings.
