Zulu Time Zone

Offset: Z is 0 hours ahead Greenwich Mean Time (GMT) and is used in Military

Coordinated Universal Time (UTC) is the world time standard that regulates clocks and time. It is successor to Greenwich Mean Time (GMT). For casual use, UTC is the same as GMT, but is used by the scientific community.
UTC is the time standard commonly used across the world since 1972. It is used in many technical fields, like aviation industry and meteorologists, also used to synchronize time across internet networks.

  • Z - is the zone designator for the zero UTC/GMT offset, also known as 'Zulu' time
  • +00 - basic short
  • +0000 - basic
  • +00:00 - extended
Email/RFC-2822: Internet Message Format Date Standard, typically used for timestamps in email headers
  • +0000 - sign character (+) followed by a four digit time providing hours (00) and minutes (00) of the offset. Indicates the zero UTC/GMT offset.

Kilo Time Zone

Offset: K is 10 hours ahead Greenwich Mean Time (GMT) and is used in Military

Daylight Saving: Clocks in Kilo Time Zone (K) do not change for daylight saving time, so K stays the same throughout the year. Other time zones may set clocks forward in summer and back in winter.
