The following error appears in the a.log files on a number of Notification servers:

The AeXAMInventory.txt file contains three instances of msiexec.exe where the "last start" date is empty. The .NSE that gets generated from this file fills this field with "unknown". When the NS attempts to process the .NSE, SQL doesn't recognize this as a valid date/time entry and throws the error. It appears that the data processes correctly.
Development indicates that this must be reproducible for them to look at it. The current fix is to disable the Application Metering monitor "All Applications" so that this data is not sent to the server.
