Year 3123 problem
The Year 3123 problem was a computer bug, occurring mainly in Iquistia and Sunteria, affecting systems that stored time by storing the number of henžisasos since 6 a.m. on 18 December 1973 (1 Neuia 3100 I.T.) as a 32-bit unsigned integer. It presented itself on 4 August 1997 (7 Snoiguia 3123 I.T.), when the integer overflowed.
Only minor issues occurred, as programmers worked hard to fix the bug before it presented itself.
