About time zones
The world is divided into about 38 time zones, ranging from UTC−12 to UTC+14. Most are offset from Coordinated Universal Time (UTC) in whole hours, though a few use 30- or 45-minute offsets — India is UTC+5:30, Nepal UTC+5:45, parts of Australia UTC+9:30.
Many regions also observe daylight saving time, shifting their clocks forward by an hour in spring and back in autumn. The cities listed here automatically follow their local DST rules — the times you see are always correct for "right now" in that city.
Working across time zones
If you collaborate with people in another country, knowing their local time helps you avoid 6 a.m. meetings. The world clock above updates every second so you can glance at it before sending that "got a minute?" message.
How accurate is this?
iAlarmClock uses your computer's clock (synced with a network time server by your operating system) and the IANA time zone database built into your browser. As long as your system clock is correct, the times shown are accurate to the second.
