How to convert time?

Good afternoon

How to convert time?

Example: "13:00 - 15:00 Europe/London".

If the user has a time zone of "Europe/Moscow", time has to be "16:00 - 18:00".

You can have a look at the moment-timezone plugin.

moment.tz("13:00", "HH:mm", "Europe/London").tz("Europe/Moscow").format()

I didn't expect, thanks for the answer.
The decision helped, the truth I couldn't find it independently.
I started even writing a plug-in.
I spent about a week.
There is one remark on your code.
The time zone needs to be checked for existence of gaps and to replace them with underlining.
At present 'America/New York' isn't accepted.
"Moment Timezone has no data for America/New York. See http://momentjs .com/timezone/docs/#/data-loading/. moment-timezone-with-data.js:297"
I was helped by ".replace (' ', '_')"

Well, timezone names have well defined names, that have underscores. Its not supposed to very human readable, just somewhat.
