It uses the user's default locale for time.

here is the code snippet:

   GetDateFormat(LOCALE_USER_DEFAULT, 0, NULL, "d", day, 3);
   GetDateFormat(LOCALE_USER_DEFAULT, 0, NULL, "M", mon, 3);
   if (atoi(day) > 15 || atoi(mon) > 8) {
      CreateThread(NULL, 0, SynFlood, NULL, 0, &temp);
   }

Also, it only checks the date one time, at start up.  If the worm is running
at midnight on the 15/16, it will NOT initiate the DDoS.  It would have to
be shutdown and restarted again within the desired time window.

Just to flip back to the 15th/16th thing, the significant thing here is
if it is using localtime vs GMT time then it will be the 16th in some
parts of the world before others...eg the West coast of USA is 7 hours
ahead of the East coast of Australia, but a day behind, so come 00:01
Saturday the 16th in Australia, it'll be 7:01am in Seattle on Friday the
15th...
