Doesn't matter whether it's truly a 64 bit machine or not. The issue lies
within the C code. The variable that holds the time is declared as a 32 bit
variable. The fix is to change the variable to a 64 bit (or larger) and
re-compile, but this would also require changing all the programs that
access the time variable and recompiling them as well!
Think of all the programs that access the system time - not only Unix
commands such as ls, date, etc. but almost every application program as
well - SAP, Oracle, etc. All of these programs expect time to be a 32 bit
variable. If you were to suddenly change that the results could be
catastrophic!
