BST can mean something else
Time zone abbreviations are not unique. Besides British Summer Time, BST is also used for:
- Bangladesh Standard Time (UTC +06:00) — Bangladesh, all year
- British Standard Time (UTC +01:00) — the UK all year from 1968 to 1971 (historical)
When the difference matters — meeting invites, software, contracts — write the UTC offset (UTC +01:00) or an IANA zone name such as Europe/London instead.
