At a healthcare system I worked at, the EMR would be shut off for the repeated hour in the fall. I'm not sure if it was because the EMR couldn't handle it (very possible, since all EMRs are shitty) or if it was the human factor that was the problem.
But the system can't solve the core problem - taking an hour out, or adding a duplicate one in, is highly disruptive to nurses already very busy schedules, and introduces multiple sources of potential confusion in patient care.
