With gawk you can do something like that :
Code:
awk -v Keep=30 -F'|' '

function stime(date   ,d,mdate) {
   split(date, d, "/");
   mdate = d[3] " " d[2] " " d[1] " 00 00 00";
   return mktime(mdate);
}

BEGIN {
   secs_in_day   = 24 * 3600;
   current_stime = systime();
   today_date    = strftime("%d/%m/%Y", current_stime);
   today_stime   = stime(today_date);
   limit_stime   = today_stime - Keep * secs_in_day;
   limit_date    = strftime("%d/%m/%Y", limit_stime);

   print "debug - Today is",today_date;
   print "debug - Keep",Keep,"days";
   print "debug - Keep datas from",limit_date,"included";

}

stime($2) >= limit_stime
