Poukisa 2038 se yon pwoblèm?
Pwoblèm ane 2038 la te koze pa processeurs 32-bit ak limit yo nan sistèm yo 32-bit yo pouvwa. … Esansyèlman, lè ane 2038 la frape 03:14:07 UTC le 19 mas, òdinatè yo toujou ap itilize sistèm 32-bit pou estoke ak trete dat ak lè a p ap kapab fè fas ak chanjman dat ak lè a.
Kouman pou mwen jwenn timestamp Unix aktyèl la?
