Reminders fire at wrong time for UTC+5:30 (India) timezone

[mdmohsin7]

Bug

Reminders fire at the wrong time for users in the India timezone (Asia/Kolkata, UTC+5:30). The offset is consistently +5.5 hours, indicating the reminder due time is being interpreted as UTC instead of the user's local timezone before storage.

Steps to reproduce

1. Set timezone to Asia/Kolkata (UTC+5:30)
2. Create a reminder via conversation (e.g. "remind me from 5pm to 7:30pm")
3. Observe the reminder fires at 11pm instead of 5pm

Expected behavior

Reminder fires at the user-specified local time (5pm IST).

Actual behavior

Reminder fires 5.5 hours late (11pm IST), consistent with the UTC+5:30 offset being applied in the wrong direction — local time treated as UTC.

Details

• Platform: iOS
• Timezone: Asia/Kolkata (UTC+5:30)
• Frequency: Every time, not a one-off
• Likely area: Reminder due time parsing in conversation processing
