==time_t parties==
 
Unix enthusiasts have a history of holding '''time_t parties''' to celebrate significant values of the Unix time number. These are directly analogous to the [[new year]] celebrations that occur at the change of year in many calendars. As the use of Unix time has spread, so has the practice of celebrating its milestones. Usually it is time values that are round numbers in [[decimal]] that are celebrated, following the Unix convention of viewing time_t values in decimal,. but amongAmong some groups round [[binary]] numbers are also celebrated, such as 1000000000000000000000000000000+2<sup>30</sup> which occured at 1310:37:04 [[UTC]] on [[January 10]], [[2004]].
 
The events that these celebrate are typically described as "N seconds since the Unix epoch", but this is inaccurate. As discussed above, due to the handling of [[leap second]]s in Unix time, the number of seconds elapsed since the Unix epoch is slightly greater than the Unix time number, for times later than the epoch.
