   To minimize the log size only a changed state is logged. The logged timestamp is matching the beginning of its measurement period.  
   When not on power saving mode a movement is detected nearly instantaneous and the detection of a no movement period is delayed by the minimal no movement duration. To match the beginning of the measurement period a cached timestamp (_sleeplog.firstnomodate_) is logged.  
-  On power saving mode the measurement period is fixed to 10 minutes and all logged timestamps are also set back 10 minutes.
