Dates entered with the datetime picker using a time zone of `"IST"` are not displaying properly in posts. They look ok in the editor preview, but they break in the rendered page, throwing a red banner for site admins and showing the time as though it were UTC instead. Things all work ok if I use the IANA `Asia/Kolkata` tz. Here’s the reproducer: `[date=2024-01-18 time=03:00:00 timezone="IST"]` → 2024-01-17T21:30:00Z `[date=2024-01-18 time=03:00:00 timezone="Asia/Kolkata"]` → 2024-01-17T21:30:00Z Displays as: ![image](https://global.discourse-cdn.com/meta/original/4X/b/4/8/b480d7f6792269f8726b95f91a5fd4625189166b.png) ---

Thank you for reporting this bug. I looked into this problem and 3 time zones had this issue: IST, KST and JST. The bug was fixed in this PR: [https://github.com/discourse/discourse/pull/26252](https://github.com/discourse/discourse/pull/26252) ---
