This attribute specifies whether the measurement intervals for the Loss Measurement session are aligned with a zero offset to real time. The value 'true' indicates that each Measurement Int starts at a time which is aligned to NE time source hour if the interval is a factor of an hour, i.e. 60min/15min = 4. For instance, a measurement time interval of 15 minutes would stop/start the measurement interval at 0, 15, 30, and 45 minutes of an hour. A measurement interval of 7 minutes would not align to the hour since 7 minutes is NOT a factor of an hour, i.e. 60min/7min = 8.6, and the behavior is the same as if the object is set to 'false'. The value 'false' indicates that each Measurement Int starts at a time which is indicated by osSoamPmGenPrflRepetitionPeriod. One side effect of the usage of this parameter is that if the value is true and the osSoamPmGenPrflRepetitionPeriod is not a factor of an hour then the start of the next Measurement Int will be delayed until the next factor of an hour.
