@PedroMD Timezones will make you insane if you work with them long enough. The thing is, a point in time is a point in time, period — the timezone is simply a local offset. A UTC date is the same point in time everywhere, though the local representation of it will vary. Libraries such as moment.js exist to convert UTC timestamps into whatever the local representation is presently, DST, etc. If you’re dealing with time at all, I’d run, not walk, to moment.js in a JS environment.
