•What Do GMT and IST Actually Mean?
GMT — Greenwich Mean Time (GMT, UTC+0) runs part of the year; the rest of the year the same clocks are on British Summer Time (BST, UTC+1) instead. People casually say "GMT" for both — SyncHours' scrubber below already resolves whichever one is actually in effect for the date you pick.
IST — India Standard Time (IST) is fixed at UTC+5:30 year-round — it does not observe Daylight Saving Time.
Timezone abbreviations like these aren't globally unique — several regions reuse the same three or four letters for unrelated zones. The scrubber above is anchored to real IANA timezone data (Europe/London and Asia/Kolkata) rather than the abbreviation text itself, so there's no ambiguity in the actual conversion.
