Convert date to secs

[vi108]

Hello All,

If a user inputs a date(mm/dd/yy) in a program, how do you convert the date to
seconds from 1/1/70 to the current time using the functions in <time.h>?

Thanks for your help.

#include <time.h>
#include <stdio.h>

int main()
{
time_t ntime;
time(&ntime);

printf(&quot;sec since 1/1/70: %u&quot;, ntime);

return 0;
}
