While you are right about this, I don't think that it even got there,
because resetTime was actually 0 when the switch from 3 ("ready") to
2 ("present") occurred:
Apr 7 09:06:41 vdr vdr: [4862] ms: 3
Apr 7 09:06:41 vdr vdr: [4862] resetTime1: 0
Apr 7 09:06:41 vdr vdr: [4862] ms: 2

Closing brackets are of course indented, since they are part of
the block. But I guess this is a philosophical argument, so let's not
get into this ;-)
