Stop converting time in your head! See local, military, and UTC time (GMT and Zulu time zones) with a tap. Developed by pilots who can never remember the current UTC (GMT/Zulu) time conversion, Pilot Time instantly gives you the current time and date for your zone, plus UTC time. Pilot Time can: - Compare the time and date at your current location (in 12-hour format and 24-hour format) to UTC time. - Show the 3 time zones you looked at most recently, plus UTC time. - Quickly convert any past, current, or future time to or from any time zone (including GMT). And selecting time zones is easy: first find the continent, then the city you want. No more mental calculations. (The time is provided by your phone's operating system, not a central server. Time zones are taken from the IANA Time Zone Database.)
