View on AmazonHow the World Clock works
- The clock reads your device's current time in UTC.
- It adds each listed city's offset to display local time for that city.
- Times refresh automatically every few seconds.
Formula / logic
Not formula-based — each city's time is your current UTC time plus that city's fixed UTC offset.
Worked example
If it's 12:00 UTC, Tokyo (UTC+9) shows 9:00 PM the same day, while Los Angeles (UTC-8) shows 4:00 AM.
