The Unix time format  might be an unsuitable time representation for
applications which require clock precision or time precision within a
few seconds  for the purposes of Timestamping or synchronizing events
 down to a  Per-Second or   Subsecond resolution.

Suggest revising Unix/POSIX   Time implementation to use a 3-Tuple
representation of calendar time,  instead of a single Integer.

typedef   int64_t  time_t [3];

 [  Delta from Epoch  in Seconds,  Delta in Microseconds,
Cumulative  Leap Adjustment from the Epoch in Microseconds]

Thus to compare two  timestamps  A and B

long long difference_in_seconds(time_t A, time_t B) {

return  (B[0] - A[0])  +   ( B[1] - A[1]  +  B[2] - A[2] ) /1000000;

}
