Time format conversion problem

[Peter Lim]

I'm having a bit of problem with time in C. Consider the following 
program fragment.


#include <time.h>

struct	tm	the_time;
long	time_in_long;

/* To convert time_in_long to the_time, I use .... */
the_time = localtime (&time_in_long);

/* To convert the_time to time_in_long, what do I do ?? */
time_in_long = XXXXXX (&the_time);


I found that in Microsoft or Zortech C, XXXXXX() is mktime(); but
I need to move the program to a UNIX environment which doesn't have
mktime(). So, I'm stuck.

Anybody know which library function works the same as mktime(), 
or have some C code to replace the function ??

My UNIX manual says that time_in_long should store the value of the
time in seconds from 00:00:00 January 1, 1970. If this help ?
