Below is a C program (sdate.c) we use in our operations to print out the
current date string in GrADS format -- e.g., 08mar2001. We have a
descriptor file template with "XXX" in place of the date, then in a
shell script, we invoke sdate, then use 'sed' to change the XXX to the
current date. Like this: 

#!/bin/sh
gdate=`/your_path_to/sdate`
...
sed s/XXX/$gdate/ /your_path_to/ctl.template > ./tmp
... 

Hope that helps!

char sname[50];

  tt = time((long *)0);
  tsec = &tt;
  tm = gmtime(tsec);
  if (tm->tm_year>99) tm->tm_year = tm->tm_year-100;
  sprintf
(sname,"%02i%s%4i",tm->tm_mday,cmons[tm->tm_mon],tm->tm_year+2000);
  printf ("%s\n",sname);
}
