dt1 = TimeLocal()+2;
do
{
  dt2 = TimeLocal();
}
while(TimeSecons(dt2) < TimeSecons(dt1));

Just cast values to ulong and make sure to multiply TimeGMT() with 1000

for print result cast to string :

ulong time = (ulong) TimeGMT()*1000 - (ulong) GetTickCount() ; 
Print("milliseconds: ",  (string)time);
