Function : Time
TimeDateDifference - Difference between two TIMEDATE values.
#include <misc.h> LONG LNPUBLIC TimeDateDifference( const TIMEDATE far *t1, const TIMEDATE far *t2);
This function returns a long integer value containing the difference in seconds between two TIMEDATE values. The values are normalized to a common time zone for the calculation. If the first argument is greater than the second, the returned value is a positive LONG. If the first argument is smaller than the second, the returned value is a negative LONG.
Parameters : Input : t1 - A pointer to a TIMEDATE structure containing the first binary value.
t2 - A pointer to a TIMEDATE structure containing the second binary value.
Output : (routine) - Returns a LONG containing the diffence in seconds.
Sample Usage :
/* Obtain the difference in SECONDS between two TIMEDATEs */ time_delta = TimeDateDifference(&binary_td2,&binary_td1);
