Maybe we should consider doing this.

I was thinking a bit on this.
As I understand, there is no problem with synchronizing hardware with system clock. It can be done whenever and how many times we want.
It looks to me that best solution would be to synchronize hardware clock with system clock as soon as we set system clock (just in case anything goes wrong later) and additionally to synchronize it also when we power off device, to maximize long term clock accuracy.
In this way we get best from both options. And it shouldn't be a problem, as we can synchronize hardware clock whenever we want.
