The military time zones are a standardized, uniform set of time zones for expressing time across different regions of the world, named after the NATO phonetic alphabet. The Zulu time zone (Z) is equivalent to Coordinated Universal Time (UTC) and is often referred to as the military time zone.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
24-hour digital clock in Miaoli HSR station.. A time of day is written in the 24-hour notation in the form hh:mm (for example 01:23) or hh:mm:ss (for example, 01:23:45), where hh (00 to 23) is the number of full hours that have passed since midnight, mm (00 to 59) is the number of full minutes that have passed since the last full hour, and ss (00 to 59) is the number of seconds since the last ...

Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+8), Cuba Standard Time (UTC−5), and (North American) Central Standard Time (UTC−6), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in an earlier ...
The United States military uses four formats for standard military correspondence: Abbreviated Format 1- or 2-digit day, 3-letter abbreviation for the month, and 2-digit abbreviated year (e.g. 4 Feb 23); Standard Format 1- or 2-digit day, the spelled out month, and 4-digit year (e.g. 4 February 2023); and for correspondence with civilians a ...
DDHHMMSSZmmmYY - Full time (used for software timestamps) DDHHMMZmmmYY - shortened time (used e.g. for timestamps manually written) DDHHMMZ - short time (e.g. used for planning) Z references the military identifier of time zone: UTC-12: Y (e.g., Baker Island) UTC-11: X (American Samoa, Niue) UTC-10: W (Honolulu, HI) UTC-9: V (Juneau, AK)
"This is a list of time zone names" should likely be changed to something more like "This is a list of military designations for given UTC offsets". For example, the Canadian Forces treat Romeo and Quebec as offset designations (-0500 and -0400 respectively), and use the local time zone (Eastern) when referencing a timezone.
Coordinated Universal Time ( UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and ...
Unit of time. A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the caesium atom. The exact modern SI definition is ...
