Support of IANA timezones

[s-aleinik]

Why it is needed?

Hi!
I was not sure if it's a feature request or a bug report, but here it is:

On our project we using react-native-localize together with date-fns-tz. And we have faced the problem during last review by apple.

I have opened issue for date-fns-tz repo previously and here's their response: marnusw/date-fns-tz#241

After this long intro my question is: is it possible to add support for getTimeZone function to return the time zone in a given format (INAA, for example). In order to prevent unexpected crashed and improve UX of date formatting.

Possible implementation

Provide optional value of format to getTimeZone function. And add mapping of aliases to zone ID according to https://nodatime.org/timezones

Code sample

@s-aleinik Currently, this returns NSTimeZone name property.

You can find additional informations here:

Time zone database entries such as “America/Los_Angeles” are IDs, not names. An example of a time zone name is “Pacific Daylight Time”. Although many NSTimeZone symbols include the word “name”, they actually refer to IDs.

I also found this article with some kind of solution.
