We utilize the DTE block to reset totalizers and schedule certain time-of-day daily or per-shift events, for example analyzer auto calibrations.
So this weekend, in many places, local time will "fall back" from "Daylight Savings" to "Standard" time. Invariably, DeltaV DTE blocks set to activate repeatedly at a specific time of day, say at shift change or midnight, will have their TE_TIME_STR parameters maintain the "interval" - and the TE_TIME_STR setpoints will shift one hour.
We'll spend a couple hours or so on Monday seeking out all the DTE blocks in the configuration and setting their setpoints back to the time of day we wanted.
Is there a way to get these setpoints to retain the time-of-day setpoint across the DST-to-standard time adjustment?
