I'm not sure if this is exactly what you're looking for for timing
(and I don't know about the date), but here's a little subroutine
that is callable from both fortran and C that I use for measuring
CPU time.

/*                                   */
/* Use unix routine"times"to measure */
/* user execution time between       */  
/* calls to second in seconds.       */  
/* Callable from FORTRAN and C.      */  
/* Returns double precsion (real*8)  */
/* in FORTRAN and double in C.       */  

/* FORTRAN callable version */
static int holdtime,flagtime=1;
double second_()
{
/* just call C version */
   double second();
   return second();
}

/* C callable version */
double second()
{
#include <sys/types.h>
#include <sys/times.h>
#include <sys/param.h>
   clock_t times();
   clock_t t;
   struct tms t1;

/* call "times" */
   t=times(&t1);
/* user time in 1/HZ seconds is in tms_utime */
/* HZ is in sys/param.h */
   return ((double)t1.tms_utime)/HZ;
}
