Save Mud Time [by Chuck Reed]

Hey, I noticed that the mud's date always reset when the game restarted.
This is what I did to fix that.

Add this to structs.h:
----------------------

struct time_write {
   int year, month, day;
 };


Put this right under the line "tics++" in comm.c:
-------------------------------------------------
write_mud_date_to_file();

Add this function and prototype it in comm.c:
---------------------------------------------

void write_mud_date_to_file(void)
{
   FILE *f;
   struct time_write date;

   f = fopen("etc/date_record", "w");
   date.year = time_info.year;
   date.month = time_info.month;
   date.day   = time_info.day;
   fwrite(&date,sizeof(struct time_write),1,f);
   fclose(f);
}

Add this line in the reset time function right after time_info = <blah> in
db.c:
----------------------------------------------------------------------------
read_mud_date_from_file();

Add this function and prototype it in db.c:
-------------------------------------------
void read_mud_date_from_file(void)
{
   FILE *f;
   struct time_write read_date;

   f = fopen("etc/date_record", "r");
   if(!f) {
      log("SYSERR: File etc/date_record not found, mud date will be reset
to default!");
      return;
   }

   fread(&read_date, sizeof(struct time_write), 1, f);
   time_info.year = read_date.year;
   time_info.month = read_date.month;
   time_info.day   = read_date.day;
   fclose(f);
}
