Reading this writeup, the procedure takes up to two minutes:
* each person in the room pulls up the stem when their individual second hand is pointing at 0, and also sets the time to the prearranged hour/minute,
* then everyone waits a bit longer until this is done;
* after another minute, everyone pushes down the stem simultaneously
Is there an alternative where you could have some way to force your second hand to the 0 position rather than waiting up to a minute for it to get there on its own then freeze it?
I do see why hacking is nice for time zone changes.
