How many seconds? In many cases, we can do this in 11 seconds (and there is
talk now about residual slew time).
The trick is that there are 2 things going on during that startup. One has
to do with "what time is it now?", and the other is "what frequency are we
operating at?" Without this last bit of information, we could tell somebody
the wrong time when they ask for it a few seconds later.
I would like to talk more with you about this.
