OK, I hear you, but I believe most critical meds are dispensed by devices that will be working on a time INTERVAL instead of clock-time. And most of these also will be for a defined period and not permanent. So, the device time versus clock time is maybe not all that critical?
Unless you are in a situation of providing legal depositions such as we are at this 'point in time', (sorry, but I've never been questioned regarding ST or DST), it may not be all that critical.
I have a number of meds that I need to take on a daily or twice-daily schedule, but my doctor has never mentioned any need for a specific hour, but rather at an interval such as take the med the night before going in to the lab for a blood draw in the morning.
The 'value' of DST may just be in leaving things alone instead of triggering all of the side effects of all the system changes to undo it. How many of you recall the angst of the Y2K century change? Do you want to go through that again?
