We are experiencing a recurring and inconsistent issue in our Jira Cloud instance where comment timestamps and SLA timings are not displaying the correct local time (Asia/Kolkata), even though:
All users have their profile time zones set correctly to Asia/Kolkata
The SLA calendar is configured properly with defined working hours (Mon–Fri, 9 AM–6 PM)
No VPN is being used
System and browser times are verified as correct
Users are from the same region, not remote
The issue is affecting multiple users across different projects
Comments are manually added (not from automation)
Issue Pattern:
The issue started about a week ago
Initially appeared for a few hours, then disappeared
Came back again on Friday, resolved itself, and then reappeared the next morning
Currently, Resolved again

The timestamps shown (e.g., 7:30 AM) are earlier than the actual comment time
We’ve tried clearing browser cache, tested in incognito, and on different browsers – the problem still persists.
