Hey,
The best place to find what properties are being used to populate a database's field is the Database Options window. This is the same window you used to enable database logging. To find the property that is populating the START_DATE_TIME field, select the UUT_Result table in the Statements tab of the Database Options window. Click on the Columns/Parameters tab and select the the START_DATE_TIME property. In the Expression textbox you will find the properties that are being used to populate that field. In the case of START_DATE_TIME the property is:
Str(Logging.StartDate.Month) + "-" + Str(Logging.StartDate.MonthDay) + "-" + Str(Logging.StartDate.Year) + " " + Str(Logging.StartTime.Hours) + ":" + Str(Logging.StartTime.Minutes) + ":" + Str(Logging.StartTime.Seconds)
As you can see it is not a single property that is used to generate this information, but a number of different properties.
