Every friday machines are turn off at 4:30 pm (end of shift) and then are turn on 7:30 pm for the night shift, in 2 of this machines I have groov rio modules, the time changes in the module due to the outage of the supply voltage, I need to know if there is a way that can maintain the same time in the moment that we energize again the module? At this moment when I arrive Monday I need to correct the time
