PHP has a function for that: timezone_name_from_abbr

In general, you should not do this. Time zone abbreviations are often ambiguous. CST has 5 different interpretations, etc. See this list.

Functions like timezone_name_from_abbr exist in PHP, but they only return the first of the time zones that happen to match.

`timezone_name_from_abbr()` not working properly. Any solution for this? – Rejoanul Alam Oct 21 '15 at 05:18
Don't try to parse a time zone abbreviation. It may work in some contexts, but it will fail in those you're not considering. – Matt Johnson-Pint Oct 21 '15 at 06:28
