Date/Time Expires Within N Seconds/Minutes/Hours/Days

Demonstrates the how to tell if a date/time is within N seconds, minutes, hours, or days of the current system time. C

#include <C_CkDateTime.h>

void ChilkatSample(void)
    {
    HCkDateTime dt;
    BOOL b;

    dt = CkDateTime_Create();

    //  Set to the current system date/time.
    CkDateTime_SetFromCurrentSystemTime(dt);
    printf("Now: %s\n",CkDateTime_getAsTimestamp(dt,TRUE));

    //  Add 10 minutes, making the date 10 minutes in the future.
    CkDateTime_AddSeconds(dt,600);
    printf("10 minutes from now: %s\n",CkDateTime_getAsTimestamp(dt,TRUE));

    //  Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
    b = CkDateTime_ExpiresWithin(dt,10,"seconds");
    printf("Expires within 10 seconds: %d\n",b);

    //  Does the date/time expire within 5 minutes?
    b = CkDateTime_ExpiresWithin(dt,5,"minutes");
    printf("Expires within 5 minutes: %d\n",b);

    //  Does the date/time expire within 15 minutes?
    b = CkDateTime_ExpiresWithin(dt,15,"minutes");
    printf("Expires within 15 minutes: %d\n",b);

    //  Does the date/time expire within 1 hour?
    b = CkDateTime_ExpiresWithin(dt,1,"hour");
    printf("Expires within 1 hour: %d\n",b);

    //  Does the date/time expire within 1 day?
    b = CkDateTime_ExpiresWithin(dt,1,"day");
    printf("Expires within 1 day: %d\n",b);

    //  Output:
