AEST is the abbreviation for Australian Eastern Standard Time, a time zone offset of UTC+10. It applies in
Eastern Australia (winter).
It is the standard, winter offset; in summer the same region switches to AEDT (UTC+11).
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
Australia/Sydney) or the UTC offset UTC+10 instead.
