Operations execute multiple times in Portrait Dialogue when only scheduled once



Portrait Dialogue scheduler issues

An operation scheduled to run once, starts at some random time and executes every 10 seconds until the scheduled time, then stops.  


The Database server and the Dialogue Application server had different system times.
Dialogue uses both in starting and stopping operations.  
The different system times caused the confusion.

It is imperative that all servers in a Dialogue solution are set to the same system time.
