It covers a range of about 600,000 years.

But C already has "struct timespec", a struct containing a time_t
and a count of nanoseconds.

The fact that there are two different types for representing times
(ignoring struct tm) is mildly inconvenient, but struct timespec
(added in C11) gives better range and precision than a single
integer value could in 64 or fewer bits.
