PowerCalculation Stopped Working

May 10, 2013 at 3:46 PM
Everyone of my PowerCalculator adapters have stopped returning any data - not even NaN values. This was working fine until a day or maybe two days ago. I've tried increasing/decreasing the LagTime and LeadTimes, with no change. I've also tried adding TrackLatestMeasurements=True - again, no change.

I am running openPDC 1.5.226

This and many other adapter problems occurred when the Time Domain service stopped working. OpenPDC is very dependent on good time!!!
