As you wish. But keep in mind that this is not a performance bottleneck.
I added some debug outputs to see where setupLabels is called from and it gets called 10 times when initializing the applet, including 3 times in the onCompleted method.
Even if it is a little bit off topic, here is the log (indentation was done manually and is somewhat guessed):

```
onShowDateChanged
  timeFormatCorrection
    onShowSecondsChanged
      timeFormatCorrection
        setupLabels
          00:00:00 NACHM.
    setupLabels
      00:00:00 NACHM.

onDateFormatChanged
  setupLabels
    00:00:00 NACHM.

onLastSelectedTimezoneChanged
  timeFormatCorrection
    setupLabels
      00:00:00 NACHM.

onDisplayTimezoneAsCodeChanged
  setupLabels
    00:00:00 NACHM.

onUse24hFormatChanged
  timeFormatCorrection
    setupLabels
      00:00:00

onStateChanged
  setupLabels
    00:00:00

onCompleted
  onSelectedTimeZonesChanged
    setupLabels
      00:00:00
  dateTimeChanged
    timeFormatCorrection
      setupLabels
        00:00:00
  timeFormatCorrection
    setupLabels
      00:00:00
```
