Why does millis() not work on ATTINY85

@Fvrank

 for (int p=0; p<=63; p++) {
            beginTime = millis();
            Level[Order[i]] = p;
            if (i==numled-1) { 
                Level[0]=63-p;
              } else { 
                Level[Order[i+1]] = 63-p;
              }
            endTime = millis();

So you want that code to run one time a second?
