About World Time on QuanQiuShiJian
QuanQiuShiJian.com (“Global Time”) provides real-time clock data for more than 7,000 cities across 24 time zones. Every clock on this site is synchronized to network time and rendered in your browser each second, so what you see is the current time, not a cached snapshot.
Time zone identifiers and daylight saving transitions come from the IANA tzdata database — the same source used by operating systems and major programming languages. Sunrise and sunset times are computed from each city’s latitude and longitude with the NOAA solar algorithm, accurate to the minute. Public holiday schedules for 14 countries are cross-checked against official gazettes and reviewed weekly.
