What Time is it Clock

It'?s the time.

Master clock of the US Naval Observatory. The people who built the first clock didn't know exactly what time it was. They had the opportunity to define it instead. Summer time is automatic. Anytime you don't know the time when someone asks you what time it was.

If we change our clocks.

On polar evenings or on polar holidays it is necessary to use a 24-hour dial instead of 12. The time of night is expressed in 24-hour notes in the format hh:mm (e.g. 01:23) or hh:mm:ss (e.g. 01:23:45), where hh (00 to 23) is the number of full consecutive clock pulses that have elapsed since the middle of the night, mm (00 to 59) is the number of full consecutive clock pulses that have elapsed since the last full clock pulse, and ls (00 to 59) is the number of seconds since the last full clock pulse.

Historically, some EU member states have used the point on the line as a delimiter, but most of the time quotation norms have since been converted to the internationally accepted double point. No delimiter is used in some context (including the US Army and some computer logs) and timestamps are spelled such as "2359".

The 24-hour notes start the 24-hour version at 00:00, and the last minutes of the 24-hour version start at 23:59. If necessary, the 24:00 format can also be used to reference late-night at the end of a certain date[5] - that is, 24:00 of a given date is the same time as 00:00 of the following one.

24:00 is mainly used to relate to the precise end of a specific date within a time period. Some train schedules also show 00:00 as the time of leaving and 24:00 as the time of arriving. Lawful agreements often run from the starting date at 00:00 to the ending date at 24:00. Noteings beyond 24:00 (e.g. 24:01 or 25:00 instead of 00:01 or 01:00) are not common and are not included in the applicable norms.

Computer displays time in 24-hour format by standard in most states. Microsoft Windows and MacOS, for example, only enable 12-hour markup by setting a computer to a fistful of certain languages and regions by setting the standard. This 24-hour system is often used in text-based workstations. Described in English in American and Canadian terms, soldier time is a byword for the 24-hour clock.

The time of night in these idioms is usually indicated almost entirely in the 12-hour clocks, which count the daily hour as 12, 1, ...., 11 with the a. m. and p. m. extensions and distinguish the two daily repeats of this series. Twenty-four hour clocks are only used there in some special fields (military, aeronautics, shipping, tourism, weather, space, computer science, logistic, rescue and hospital services) where the ambiguity of 12-hour notes is considered too unfavourable, unwieldy or hazardous.

There are some differences between the use of the U.S. and English-language armed forces for the purpose of force management and other 24-hour time systems: There is no hour/minute delimiter used when the time is typed and a character with the name of the time region is added (e.g. "0340Z"). Leaders are always spelled out zeroes and must be pronounced, i.e. 5:43 a.m. "zero forty-five" (casual) or "zero five four three" (military), as against " five forty-three" or "five four three three three".

The NATO telephone system is used to mark army time areas with letters and thus with wording. Like, 6:00 a.m. US Eastern Standard Time (UTC-5) would be spelled "0600R" and pronounced "zero six hundred Romeo". Locally the time is called J or " Juliett ". "1200J " ("twelve hundred Juliett") is lunch time, city time.

The Greenwich Mean Time (or Coordinated Universal Time) is referred to as Time Z and therefore as Zulu Time. Use of the 24-hour clock has increased in Britain since the beginning of the twentieth centruy, although efforts to make the system formal have more than once miscarried. In 1934, the BBC changed to the 24-hour clock for radio advertisements and program lists.

After five month of disappointment from the general audience, the experiments were stopped and the BBC kept using the 12-hour clock. In the same year, US carriers Pan American World Airways Corporation and Western Airlines introduced the 24-hour clock. Today, the BBC uses a mix of 12-hour and 24-hour clocks.

British Rail and London Transport changed to the 24-hour timetable in 1964. A mix of 12- and 24-hour clock can also be found in other English-speaking Commonwealth countries: In Canada, the 24-hour clock is much more widely accepted by people who speak fluent English, and Australia also uses both of them.
