16.5.1.2 Data records

Subsequent rows are called data records. They include observed data and associated record
keeping. The first field is a time stamp (TS), and the second field is the record number (RN).
The time stamp shown represents the time at the beginning of the scan in which the data is
written. Therefore, in record number 3 in the previous
the average of the measurements taken over the minute beginning at 14:26:01 and ending at
14:27:00. As another example, consider rainfall measured every second with a daily total rainfall
recorded in a data table written at midnight. The record time stamped 2019-03-08 00:00:00 will
contain the total rainfall beginning at 2019-03-07 00:00:01 and ending at 2019-03-08 00:00:00.
NOTE:
TableName.Timestamp syntax can be used to return the timestamp of a data table record,
expressed either as a time into an interval (for example seconds since 1970 or seconds since
1990) or as a date/time string. For more information,
