Analysis timerule option: Add a possibility to make the timerule conservative. Emit calculation events only if the snapshot time of all inputs are more recent than the planned calculation time.

Now the TimeRules Natural and Periodic emit events to the Data PIPE in

case NATURAL: an event is received by one of the selected inputs

case PERIOD: when a certain timespan elapse.
Both method doesn't take into account that some input of the analyses are received later. So the input values of a certain calculation timestamp are different if you calculate them later (even when you configure no compression on all according attributes).
Pro:
It is very ease to transform high resolution data into low resolution data based on averages on a fixed timespan without loss of accuracy.
If the calculation becomes stale you have the insighed that some inputs become stale.
