(32bit and 64bit... no limit (for human's concern)) |

:The date is internally stored as seconds from the year 1970 (more or less). I've computed (2038-1970)*365*24*3600, obtaining 2144448000; now, we are near the limit for a 32bit signed integer... but not to the limit of a 64bit signed integer. I take a note for the day I will ask myself is it is worth buying a 64bit hardware :) About the 2121, 64bit systems still can :) With a 64bit signed int, you can really go a lot further --[[User:ShinTakezou|ShinTakezou]] 15:22, 12 December 2008 (UTC) |
