How much effort(?sp) would it be to limit it to one channel 
which is allowed to be used to set system time?

That sounds easier and more "strait forward" than
a fuzzy recorder reaction on time warps...



Where can that be defined?

Maybe it can be compiled into, or only the first three(?)
channels are allowed to set the system time?


I'm not sure if it's still true, but "terrestically" ZDF have (had?) to 
transmit the correct time, they ajusts (-ed?) the 15,625kHz 
line frequency with the PTB-Cs-timebase too. (That's not "well known"
but there are/were high precission time bases which synchs on the 
ZDF-TV-Signal.)
On Satellite that might be defined other, but i think that the ZDF will
use the same (exact) clocks as terristic with a little 200ms offset..?)

And:
it's known that "commercial" stations don't want to support
VCRs and never transmits the right time (not speaking of
VPS and VCR stop signals during commercial breaks...)
