Subject: | OS X's 64 bit time.h broken for very distant dates |
Long story short, OS X's 64 bit time.h, at least in 10.6.2, is off by a
day at localtime(-2**52) and gmtime(-2**52) which messes up testing.
The solution is to detect this breakage and set SYSTEM_LOCALTIME_MIN
appropriately. I don't know how far back this breakage goes.
