TimeDateDifference

Function : Time

TimeDateDifference - Difference between two TIMEDATE values.

#include <misc.h>
LONG LNPUBLIC TimeDateDifference(

    const TIMEDATE far *t1,
    const TIMEDATE far *t2);

Description :

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);
