Difference between UTC, GMT, Zulu Time, and Z
-
UTC stands for Universal Time Coordinated, and it's the primary time standard by which the world regulates clocks and time. UTC use to be called Greenwich Mean Time (GMT), but still is in English speaking countries, or Zulu Time (Z), which is used in plane and ship navigation. UTC is the time at the Prime Meridian (0° Longitude) given in hours and minutes on a 24 hour clock.
To obtain your local time you need to subtract or add a certain number of hours from UTC depending on how many time zones you are away from Greenwich. The map below shows the standard difference from UTC time to local time.
Curious why "Zulu"? It is the radio transmission articulation for the letter Z.
On Windy you can change settings to display all time in UTC. This can be done in the settings by checking "Display all time in UTC".
Also, very interesting is to see the difference between solar time (position of sun in the sky during the day) vs standard time (link).
