No, time(0) returns UTC.  The following will print UTC unless
your system clock is wrong:

#include "stdio.h"
#include "stdlib.h"
#include "time.h"
main(){
   time_t now=time(0);
   putenv("TZ=GMT0");   // ignored by time(), used by ctime()
   puts( ctime(&now));
}


It's mktime that expects local time in the tm struct and returns
UTC seconds.

Your test program works fine here.  I added the line

 printf( "timezone appears to be  GMT%d\n", (age-now)/(60*60) );

and it printed out the right numeric offset.  Notice that the
offset is calculated in the reverse order, from local to UTC
rather than the expected order.  <shrug>
