[Feature Request] World Clock Widget for Multi-Timezone Display

[karlspace]

Description

I'd like to propose a World Clock information widget for displaying multiple time zones simultaneously. This would complement the existing datetime widget for users who need to monitor times across different locations.

Working Implementation Available

A fully functional implementation is available in my fork:

• Repository: karlspace/Dashboard
• Branch: feature/worldclock
• Docker Image: ghcr.io/karlspace/dashboard:latest

To test it:

The implementation is open for anyone to review, use, or adapt. If this feature gains enough community interest, feel free to coordinate with the maintainers about potential inclusion in the upstream project.

Use Cases

• Distributed teams working across multiple time zones
• Quick overview of business hours in different office locations
• Monitoring international markets or services
• Personal use for staying connected with family/friends abroad

Proposed Features
