the "{label}" clock tile's timeZone `{zone}` is not a recognised IANA zone; falling back to the local time zone.

What happened

The clock tile's timeZone was tested by constructing an Intl.DateTimeFormat with it, and that threw. The tile still ticks, in the device's local zone, so a dashboard built for a trading floor in another zone will quietly be showing the wrong wall clock.

The fix

Use an IANA zone name such as 'Europe/London' or 'America/New_York'; abbreviations like 'EST' and offsets like '+01:00' are not zones.

The smallest fix

tiles: [{ kind: 'clock', label: 'New York', timeZone: 'America/New_York' }]
