How to use it
Use the clock to scan the current day and time across teams, family, travel stops, or launch markets.
- Enter one IANA time zone per line or use the supplied common-zone list.
- Apply the list to show each zone's current localized date, time, and UTC offset.
- Leave the page open for live updates or reset to the launch-market examples.
Worked example
- Input
America/New_York
Europe/London
Asia/Singapore
- Output
Three live rows showing local date, time, and current GMT offset
Offsets are evaluated at the current instant, so daylight-saving differences can change by date.
Method and definitions
- Every row formats the same Date.now() instant with an explicit IANA timeZone option.
- The table updates from the device clock; locale controls presentation, not the instant or zone rule.
Limits and edge cases
- Supports 1–8 unique zones and relies on the device clock and browser time-zone data.
- It is not synchronized to a network or atomic clock and makes no sub-second accuracy claim.
Privacy
Entries, dates, times, and results remain in this tab. Rigula does not upload them or add them to the URL.
