mobium timezone

This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET

Read the device timezone, or change it

With no argument, prints the current zone.

Unlike mobium call this works on real hardware. A clock that jumps a zone mid-session breaks scheduling, caching, and anything that stored a local timestamp.

Takes an IANA name. Confirmed by reading it back — an unknown zone is accepted and ignored, so the check is what makes the answer mean anything.
