| Description | Time this meter reader began its most recent data collection.
This variable should be written by a meter reader as its first
step in reading flow data. The meter will set this LastTime
value to its current Uptime, and set its PreviousTime value
(below) to the old LastTime. This allows the meter to
recover flows which have been inactive since PreviousTime,
for these have been collected at least once.
If the meter reader fails to write flowLastReadTime, collection
may still proceed but the meter may not be able to recover
inactive flows until the flowReaderTimeout has been reached
for this entry. |
