IST can mean something else
Time zone abbreviations are not unique. Besides India Standard Time, IST is also used for:
- Irish Standard Time (UTC +01:00) — Ireland's legal name for its summer time
- Israel Standard Time (UTC +02:00) — Israel, in winter
When the difference matters — meeting invites, software, contracts — write the UTC offset (UTC +05:30) or an IANA zone name such as Asia/Kolkata instead.
