Time zones, UTC vs GMT and time difference

• Time zones are geographical areas that observe the same official time
• An offset is the difference between time in a certain time zone and Universal Coordinated Time (UTC), whose predecessor is GMT
• GMT is itself a time zone that has 0 offset from UTC. Even after 1972, when UTC replaced GMT, the latter continued to be widely used in various fields (e.g. aviation and broadcasting)
• For direct practical purposes, UTC and GMT appear a lot as UTC/GMT, and they are, in clock time, interchangeable

The new time converter takes away the hard work of finding out the offset or when Daylight Saving Time (DST) is in use. It provides the time comparison based on the location(s) you choose

You can then decide which time is best for an event, conference call or meeting that other people, from different time zones, will attend as well.
