Determining meter power-up and power-down times
The audit log can be used to determine the meter start (or re-start) time and the meter power-
down time by examining the PowerFailTime record(s). The PowerFailTime record time stamp
indicates (to within a few seconds) the time that the meter was started. The ‘as-left’ value
indicates the time (to within a few seconds) that the meter was powered-down.
