What does ZULU time mean?

Zulu Time is the world time. It is also known as UT or UTC (Universal Time (Co-ordinated)). All over the planet it is the same time. There are no timezones for UTC. UTC also has no Daylight Saving Time or Summer Time. Also the date is UTC dependend. That means if you live in NewYork and it is 10pm Saturday night (standard) and you would convert the time to UTC you would get 3am Sunday morning as time and date.

UTC is used in plane and ship navigation. UTC is also used by international shortwave broadcasters in their broadcast and program schedules. Ham radio operators, shortwave listeners, the military, and utility radio services are also big users of UTC.

UTC is based on GMT (Greenwich Mean Time). Greenwich mean time was based upon the time at the zero degree meridian that crossed through Greenwich, England. GMT was first used by the Royal Navy in the 19th century.

UTC uses a 24-hour system of time notation. "1:00 a.m." in UTC is expressed as 0100, pronounced "zero one hundred." Fifteen minutes after 0100 is expressed as 0115; thirty-eight minutes after 0100 is 0138 (usually pronounced "zero one thirty-eight"). The time one minute after 0159 is 0200. The time one minute after 1259 is 1300 (pronounced "thirteen hundred"). This continues until 2359. One minute later is 0000 ("zero hundred"), and the start of a new UTC day.
