FreeBSD does suffer from a problem shared by all other 32-bit
implementations of UNIX, however -- it's clock will "roll over"
someday. The UNIX clock is implemented as a 32-bit signed integer
number of seconds since 00:00 Jan 1, 1970 GMT. According to this simple
program:
#include <stdio.h>
#include <time.h>
main()
{
time_t endEpoch = (time_t) 0x7fffffff;
printf("Time ends at %s", ctime(&endEpoch));
}
Time ends at Mon Jan 18 20:14:07 2038.
This is in MST; your mileage may vary (+/- 12 hours). The solution is,
of course, to move entirely to 64-bit processors before 2038. I think
we'll handle this one. ;^)
