Thanks for the idea, but this should be no problem.
To give some identifiers:

sscanf((char *)datum(),"%*s %s %d %s %d",monat,&tag,time_string,&jahr);

int tag;
char monat[6];
int jahr;
char *time_string;

/* (tag=day, monat=month, jahr=year)

datum() returns something like "Thu Nov 6 11:12:34 1997"

and the sscanf should get the things into the different variables

%*s omits the first (Thu)
%s writes "Nov" into monat (=char monat[6])
%d writes 6 into tag
%s writes "11:12:34" into time_string
%d writes 1997 into jahr

Ok, that's it. I think that should work, or did I misinterpret something?
