Alistair McClymont, Unix Time
Unix Time is an artwork that exists as an iPhone/iPad application. Unix Time shows a 24 hour time lapse of the sky, with one minute of real time taking one second. A long number is overlayed on the sky showing the current time in unix time, the number of seconds since midnight, 1st January 1970. Every second this number increments by 1. Unix time can be seen as the birth time of modern computing, an alternative epoch to the Gregorian.
Unix Time exists as an application for the iPhone, iPod and iPad. It shows the real time in unix time. Install Unix Time on your iPhone/iPad
Fun fact: 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. For example, at 01:46:40 on September 9, 2001, the Unix billennium (Unix time number 1,000,000,000) was celebrated.
