Time is an illusion, Unix time doubly so...

To compute the elapsed time in seconds between two given UTC dates requires the consultation of a table of leap seconds, which needs to be updated whenever a new leap second is announced. Since leap seconds are known only 6 months in advance, time intervals for UTC dates further in the future cannot be computed. Although BIPM announces a leap second 6 months in advance, most time distribution systems ( WebJan 31, 2016 · The difference of 69 seconds is caused by the difference between Terrestrial Time and UTC, currently 68.184 seconds.
