“At 15:30:08 UTC on Sunday, 4 December 292,277,026,596 64-bit versions of the Unix time stamp would cease to work, as it will overflow the largest value that can be held in a signed 64-bit number. This is more than ten times the estimated age of the universe, which is 1.3x1010 years (13.7 billion), and by this time all Earth-based systems running on 64-bit UNIX time will be long gone due to the Earth being incinerated by the red giant Sun in 7.6 billion years.”
