Abstract
A utility meter includes a consumption measurement unit for generating consumption data, a meter processor, and a RTC for time stamping the consumption data to provide interval meter data during interval meter operation. A memory stores the interval meter data. The meter processor implements/initiates responsive to a power loss that suspends RTC operation, switching from interval to relative time operation where consumption data is stored as relative consumption data together with a relative time as relative meter data. Responsive power restoration and receiving a current time, the meter switches from relative time to interval meter operation. The restoration time is calculated using the current and an elapsed time since the restoration. The time of restoration and current time is used to generate calculated times. The consumption data from relative time operation is time stamped with the calculated times to provide time-corrected relative meter data that is stored to the memory.
