How many time zones are there in the world?

36.

There are 36 time zones under the new international time standard, the Coordinated Universal Time or UTC, as listed in Wikipedia. These time zones are measured from UTC -12 to UTC+14. The UTC has replaced the Greenwich Mean Time (GMT, which had 26 time zones from GMT-12 to GMT+13) as the time zone standard in most nations of the world since 1972
