[Feature Request] Display local time and UTC timestamps in usage statistics

Feature Request

When viewing usage statistics with plot code, timestamps are currently displayed without timezone information, making it difficult to understand when activities occurred relative to the user's local time.

Current Behavior

• Usage statistics show timestamps, but it's unclear which timezone they're in
• Users must manually calculate the time difference to understand when activities happened in their local timezone

Proposed Enhancement
Add timezone display options to usage statistics with one of the following approaches:

1. Option 1 (Preferred): Configurable timezone display

• Allow users to configure which timezone(s) to display in the usage plot
• Show timestamps in the configured timezone(s)

1. Option 2: Display both UTC and local time

• Always show UTC time plus a user-configurable custom timezone
• Format example: "14:30 UTC (09:30 EST)" or "2026-01-09 14:30:00 UTC / 09:30:00 EST"

Benefits

• Users can immediately understand when activities occurred in their local context
• No mental calculation required to convert timestamps
• Especially helpful for users who work across multiple timezones
• UTC reference provides standardized timestamp for logging/debugging purposes

Technical Notes

• There appears to be sufficient space in the usage statistics display to accommodate both timestamps
• Could potentially be implemented as a user preference setting that persists across sessions
