Instead of hours and minutes, the mean solar day is divided into 1000 parts called ".beats". Each .beat is equal to one decimal minute in the [French Revolutionary][6] [decimal time][4] system and lasts 1 minute and 26.4 seconds (86.4 seconds) in standard time. Times are notated as a 3-digit number out of 1000 after midnight. So, @248 would indicate a time 248 .beats after midnight representing 248/1000 of a day, just over 5 hours and 57 minutes. There are no time zones in Swatch Internet Time; instead, the new time scale of Biel Meantime (BMT) is used, based on Swatch's headquarters in [Biel][7], Switzerland and equivalent to [Central European Time][8], West Africa Time, and [UTC+01][9]. Unlike civil time in Switzerland and many other countries, Swatch Internet Time does not observe [daylight saving time][10]. ## Contents * [1 History][11] * [1.1 Uses][12] * [1.2 Beatnik satellite controversy][13] * [2 Description][14] * [2.1 Beats][15] * [2.2 Time zones][16] * [2.3 Notation][17] * [2.4 Time unit conversion][18] * 2.5 Calculation from UTC+1 * [3 See also][19] * [4 References][20] * [5 External links][21] ## History[[edit][22]] Swatch Internet Time was announced on October 23, 1998, in a ceremony at the Junior Summit '98, attended by [Nicolas G. Hayek][23], President and CEO of the Swatch Group, G.N. Hayek, President of Swatch Ltd., and [Nicholas Negroponte][24], founder and then-director of the [MIT Media Lab][25]. During the Summit, Swatch Internet Time became the official time system for [Nation1][26], an online country (supposedly) created and run by children. ### Uses[[edit][27]] ![][28] A Swatch watch showing .beat time in the bottom part of the display During 1999, Swatch produced several models of watch, branded "Swatch .beat", that displayed Swatch Internet Time as well as standard time, and even convinced a few websites (such as [CNN.com][29]) to use the new format.[[1]][30] [PHP][31]'s date() function has a format specifier 'B' which returns the Swatch Internet Time notation for a given time stamp.[[2]][32] It is also used as a time reference on [ICQ][33], and the online [role-playing game][34] [_Phantasy Star Online][35]_ has used it since its launch on the [Dreamcast][36] in 2000 to try to facilitate cross-continent gaming (as the game allowed Japanese, American and European players to mingle on the same servers). In March 2001, [Ericsson][37] released the T20e, a [mobile phone][38] which gave the user the option of displaying Internet Time. Outside these areas, it is infrequently used. While Swatch still offers the concept on its website, it no longer markets beat watches.[[_citation needed][39]_] In July 2016, Swatch released Touch Zero Two, its second wirelessly connected watch, with Swatch Internet Time function. ### Beatnik satellite controversy[[edit][40]] In early 1999, Swatch began a marketing campaign about the launch of their Beatnik satellite, intended to service a set of Internet Time watches. They were criticized for planning to use an [amateur radio][41] frequency for broadcasting a commercial message (an act banned by international treaties). Swatch reallocated the transmitter batteries to a different function on the [Mir space station][42], thus the satellite never broadcast.[[3]][43] ## Description[[edit][44]] The concept was touted as an alternative, decimal measure of time. One of the supposed goals was to simplify the way people in different [time zones][45] communicate about time, mostly by eliminating time zones altogether. ### Beats[[edit][46]] Instead of hours and minutes, the [mean solar day][47] is divided into 1,000 parts called ".beats". Each .beat lasts 1 minute and 26.4 seconds. One .beat is equal to one decimal minute in [French decimal time][48]. Although Swatch does not specify units smaller than one .beat, [third party][49] implementations have extended the standard by adding "centibeats" or "sub-beats", for extended precision: @248.00. Each "centibeat" is a hundredth of a .beat and is therefore equal to one [decimal][50] second (0.864 seconds).[[4]][51][[5]][52] ### Time zones[[edit][53]] There are no time zones; instead, the new time scale of Biel Meantime (BMT) is used, based on the company's headquarters in [Biel, Switzerland][7]. Despite the name, BMT does not refer to mean [solar time][54] at the Biel [meridian][55] (7°15′E), but to the standard time there. It is equivalent to the [Central European Time][8] and [West Africa Time][56] or [UTC][57]+1. Like UTC, Swatch Internet Time is the same throughout the world. For example, when the time is 875 .beats, or @875, in New York, it is also @875 in Tokyo: 0.875 × 24 hours = 21:00 BMT = 20:00 UTC. Unlike civil time in most European countries, Internet Time does not observe [daylight saving time][10] and thus it matches Central European Time during (European) winter and [Western European Summer Time][58], which is observed by the United Kingdom, Ireland, Portugal and the [Canary Islands (Spain)][59], during summer. ### Notation[[edit][60]] The most distinctive aspect of Swatch Internet Time is its notation; as an example, "@248" would indicate a time 248 .beats after midnight, equivalent to a fractional day of 0.248 CET, or 04:57:07.2 UTC. No explicit format was provided for [dates][61], although the Swatch website formerly displayed the [Gregorian calendar][62] date in the order day-month-year, separated by periods and prefixed by the letter _d_ (d31.01.99). ### Time unit conversion[[edit][63]] | ----- | | Unit | Beat Conversion | | 1 day | 1000 .beats | | 1 hour | 41.6 .beats | | 1 min | 0.694 .beats | | 1 s | 0.011574 .beats | Note that units smaller than 1 .beat are not officially recognized by the standard. ### Calculation from UTC+1[[edit][64]] The formula for calculating the current time in .beats from [UTC][57]+1 is: (UTC+1seconds + (UTC+1minutes * 60) + (UTC+1hours * 3600)) / 86.4 Round down the outcome.[[6]][65] ## See also[[edit][66]] * [Decimal time][4] * [French Republican Calendar][67] * [ke][68] = 10 'beats' * [Metric time][69] * [New Earth Time][70] * [Unix time][71] * [Coordinated Universal Time][72] (UTC) ## References[[edit][73]] 1.
