GST is the abbreviation for Gulf Standard Time, a time zone offset of UTC+4. It applies in
UAE, Oman.
Time-zone abbreviations are convenient but not unique or official — several codes are shared by
more than one zone. When precision matters, use the underlying IANA zone name (for example
Asia/Dubai) or the UTC offset UTC+4 instead.
