I'm not sure what the specs on gettimeofday() since it's not supported on
WIN32, but this may be an adequate substitution. 

void gettimeofday(struct timeval* tp)
  timeb tm;
  tp->tv_sec  = tm.time;
  tp->tv_usec = tm.millitm * 1000;

Yes microseconds are not supported on WIN32.

I had a problem in timestamping transactions on an IBM 3090
where the granularity of millsecs was not enough to avoid collisions.
If that is the case then something like the following will help:

void gettimeofday(struct timeval* tp)
  static int counter;  
  timeb tm;
  tp->tv_sec  = tm.time;
  tp->tv_usec = (tm.millitm * 1000) + counter;

It depends.  If ctime(0) on Unix returns "January 1st, 1970 00:00:00" if
you reside in the EST timezone, isn't that also misleading?
Should it not return "December 31st 1969 19:00:00"? 
What does Unix return for values between 0-18000, assuming you reside
in EST5EDT land? 

Or you could just:
if (tval < _timezome) THROW(ERROR);
