Timezone conversion in php

Question

Can anyone suggest an easy method to convert date and time to different timezones in php?

Answer 1

I always struggle to remember how exactly setTimezone() method works. Is it adjusting datetime according to timezone? Or does it take a given datetime, drops its timezone, and uses the one you pass? All in all, I'd rather have a more intuitive way to work with timezones.

I like this one:

(new AdjustedAccordingToTimeZone(
    new DateTimeFromISO8601String('2018-04-25 15:08:01+03:00'),
    new Novosibirsk()
))
    ->value();

It outputs a datetime in ISO8601 format, in Novosibirsk timezone.

This approach uses meringue library, check out a quick start for more examples.
