# system.kanoa.event.clearZeroedCountEvents(assetId, tStamp, userId)

We added a zero at the beginning of a run to prevent calculated counts from occurring, but now the run has ended or a shift change has occurred.
We will see if the last entry is a zero and if so remove it, so that the count will be calculated.
If this is a shift change we will delete the zero count and then add the zero count for the next shift
