Yes, it's in seconds.  (Seconds since January 1, 1970 if I recall
correctly.)  This can be made pretty clear by doing

#include <stdio.h>
#include <time.h>

int main(void)
{
  for (;;)
    printf("Time: %ld\n", (long)time(NULL));
  return 0;
}

and noticing how often it changes.

Perhaps this should be added to the documentation.
