But it isn't 1 millisecond, it's granulatity is 1 microsecond (1/1000
millisecond, or 1000 nanoseconds)

utime -> second (time_t), same granularity as old stat(), time() and
friends.

utimes -> microsecond (struct timeval) (1/1000000), same granularity as
gettimeofday() and friends.

utimen -> nanosecond  (struct timespec) (1/1000000000), same granularity
as current stat(), clock_gettime() and friends.
