/usage and claude.ai usage displays show reset times in Pacific regardless of user timezone

Bug

Usage reset times are displayed in Pacific time even when the user and their system are in another timezone.

Environment

• Claude Code on Windows 11
• System timezone: Eastern (verified via tzutil: Eastern Standard Time; system clock correct)

Expected

Reset times in the usage displays render in the user's local timezone (or offer a timezone preference).

Actual

The 5-hour-window reset is shown as e.g. "8 PM" when the actual reset moment is 11 PM Eastern — i.e. the label corresponds to America/Los_Angeles. The underlying timestamp is correct; only the rendered timezone is wrong/fixed.

Impact

Users planning work around the 5-hour window must mentally convert timezones; East-coast users see times 3h off from their clock.

Repro

1. Set system timezone to US Eastern.
2. Use Claude enough to have an active 5-hour window.
3. Open the usage display and compare the shown reset time against the account's actual reset timestamp.
