Namespace: Gemstone.PQDIF.Logical
Assembly: Gemstone.PQDIF (in Gemstone.PQDIF.dll) Version: 1.0.138 -- Release Build+96875833d2894fd2d83b642a724995fed7d1f0b1
public DateTime StartTime { get; set; }

Property Value

DateTime

Remarks

The ObservationRecord contains two timestamp fields: StartTime and TimeTriggered. The StartTime is a required part of any Observation, whereas the TimeTriggered is optional. The StartTime does not have to be the same as the trigger time and can therefore be chosen more or less arbitrarily. For instance, you can choose to record the StartTime as the timestamp of the first data point in the observation or the top of an interval in which the data was captured. The trigger time field is more well defined, essentially always representing the point in time at which the data source decided to capture some data in the PQDIF file.

Exceptions

InvalidDataExceptionStartTime element not found in observation record.
