Time Conversion

I have 2 time values:


System time and an input from the user.


1) System time is in the form of seconds from 1/1/1970 calculated by
using


time_t secs;
SYSTEMTIME stime;


time(&secs);


2) The input from the user is in form hr:min:sec which is a string
value.


But the seperate values have been obtained by using


sscanf(storedTimeValue, "%d:%d:%d", &hour,&minutes,&seconds);


So now I have 3 integer values for hour,minutes and seconds.


3) I have a function which calculates the time difference between 2
time values,
but both these time values need to be seconds from 1/1/1970.


Is there any way by which,I could convert the user given time into time

in seconds from 1/1/1970,
so that I can get the difference between the system time and the user
given time.
