[FEATURE]: Default session title should use local time instead of UTC (Z) #22781
Closed as not planned
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
When a new session is created, the default title is formatted as:
New session - 2026-04-15T03:20:00.000Z
The Z suffix means this timestamp is in UTC (GMT+0). However, the "last modified" time shown in the session list uses local time. This inconsistency is confusing — the title makes it look like the session was created hours ago (or in the future) depending on your timezone.
Suggestion: Use local time instead of UTC in the default session title, e.g.:
New session - 2026-04-15T11:20:00
The fix would be in packages/opencode/src/session/session.ts, replacing new Date().toISOString() with a local time formatter. Happy to submit a PR if this direction sounds good.

PR #30350 has been submitted which addresses this feature request by replacing toISOString() with local-time formatting in session.ts.
