timestampToGmDateTime to convert the timestamp to a datetime and
datetimeToTimestamp to convert the datetime to a timestamp. However, these two functions are not always the inverse(e.g. now, in daylight saving time...).
Thus, the following code:
Start world = startEngine ( get currentDateTime >>= \dt->viewInformation "Original, conversion"  (dt, timestampToGmDateTime $ datetimeToTimestamp dt)) world
Does not give the same times, as it should. Therefore,
waitForTimer 1 does not wait for 0:01 but for 1:01.
I think this has to do with daylight saving time.
