New features like the ability to add more clocks and set alarm time were added recently and general usability was improved.
Furthermore, we have developed brand-new Flash Time Clocks for Europe, Australia, Canada and United States, making time check even more easy!
Greenwich Mean Time (GMT) is an older standard, adopted starting with British railroads in 1847.
Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK.
Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union.
Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system.
Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UT - in which a second was defined as a fraction of a day or year.
The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UTC. Most time zones are exactly one hour apart, and by convention compute their local time as an offset from UTC or GMT.
In many locations these offsets vary twice yearly due to daylight saving time transitions.
Flash Map of World Time displays current local time in any place around the world right now.
World Time Clock & Map is an indispensable utility for everyone who deals with people abroad or anybody who is keen on knowing what time it is further than locally.
