This is a problem.  I fixed most of the other cases in which pointers to
32-bit values were being passed in as pointers to 64-bit values.

BAD BAD BAD.

Apparently I missed at least one instance.

  time_t  tt = timeSecs;
  timePtr = localtime(&tt);

Any place where there is casting to (time_t *) is an indication that
there is probably a problem lurking behind.
