I ran this little snippet today using a 64 bit Ruby on Solaris:
Time.at(2**62)
It blew up with 'ArgumentError: localtime error'. Huh? Shouldn't it work out to (2**63-1)? Is this a bug in Ruby?
Actually, no. It turns out that localtime() is limited to years less than or equal to 2147485547 (INT_MAX + 1900), because the members of struct tm are all ints.
Why not just make the tm_ struct members unsigned longs? I have no idea.
