However, the US military prefers not to say 24:00 - they do not like to have two names for the same thing, so they always say "23:59", which is one minute before midnight. For example, you would say "Tuesday at 24:00" and "Wednesday at 00:00" to mean exactly the same time. ©/stocknshares A Standard, Not a Time Zone UTC is the time standard commonly used across the world. The Greenwich Meridian in London, England. 5:45 am UTC This page was last changed on 20 November 2018, at 23:09. The irregularity and unpredictability of UTC leap seconds is problematic for several areas, especially computing (see below ). This 24-hour time standard is kept using highly precise atomic clocks combined with the Earths rotation. UTC (on which civil time is usually based) is a compromise, stepping with atomic seconds but periodically reset by a leap second to match UT1. Primarily, UTC is based on mean solar time at the prime meridian running through Greenwich, UK. The offset is expressed as either UTC- or UTC+ and the number of hours and minutes. All time zones are defined by their offset from UTC. Midnight is called 24:00 and is used to mean the end of the day and 00:00 is used to mean the beginning of the day. Coordinated Universal Time (UTC) is the basis for civil time today. UTC Coordinated Universal Timeis the 24-hour time standard used as a basis for civil time today. Under the 24-hour clock system, the day begins at midnight, 00:00, and the last minute of the day begins at 23:59 and ends at 24:00, which is identical to 00:00 of the following day. Internally, this time formatter is implemented using the UTC methods on the Date object. Numbers under 10 usually have a zero in front (called a leading zero) e.g. The specifier may contain the same directives as the local time format. Also, the international standard notation of time ( ISO 8601) is based on this format.Ī time in the 24-hour clock is written in the form hours:minutes (for example, 01:23), or hours:minutes:seconds (01:23:45). In some parts of the world, it is called railway time. This system is also referred to (only in the US and the English speaking parts of Canada) as military time or (only in the United Kingdom and now very rarely) as continental time. You can customize the display of the clock by editing the format. The 24-hour clock is a way of telling the time in which the day runs from midnight to midnight and is divided into 24 hours, numbered from 0 to 24. O Tempo Universal Coordenado (abreviado internacionalmente como UTC, um meio-termo entre o inglês Coordinated Universal Time e o francês Temps Universel Coordonné 1 2 3 ), também conhecido como tempo civil, é o fuso horário de referência a partir do qual se calculam todas as outras zonas. Since llGetWallClock () returns Pacific time and llGetGMTClock () returns UTC and that counts seconds since midnight, this script shows time in UTC, Eastern Time, Central Time, Mountain Time, Pacific Time, Alaska time, Hawaii time, CET, EET or Moscow time.
