Support switching timezones for formatting the timestamps in the logs.

Request

As the title says.

This will help reduce cognitive load for log-viewer users who need to correlate log events with their local time or a specific reference time. Currently, log timestamps are displayed in a fixed timezone (e.g., system default), which may not align with the user's working context. This makes it difficult for users to quickly interpret and correlate log events with real-world occurrences, especially when working across different time zones.

Possible implementation

See the implementation at https://github.com/junhaoliao/yscope-log-viewer/tree/beta-release

Currently, the implementation includes:

• A toggle that allows users to switch between UTC and "Local" time, where "Local" refers to the user's browser timezone.

We aim to enhance this functionality by:

• Introducing a dropdown list that lets users select a specific timezone.
• Providing helpful hints within the dropdown to indicate:
  • The user's browser timezone.
  • The logger's timezone, typically available as time-zone difference packets in CLP IR logs.

This improvement will offer greater flexibility and clarity for users working with logs across different time zones.
