Is there any way of knowing exactly when the zone stops operating ?
If my watch says 1830 will I still have to pay. Is there a couple of
minutes leeway or can I synchronize my watch with TFL ?

Nice watches, use both MSF and DCF but not as sensitive as some other
models. However TFL did miss a trick (deliberately?) by not actively
signalling the zone. If Casio say 18:30 (from Feb 19 18:00) but you
get a ticket, who trumps whom? They can't get times on pay & display
machines right (compare display times with said Casio: some are
minutes out).

Even the Swiss can't get it right -- the ticket machine at CERN
was always stamping tickets 5-10 minutes early.

The railway clocks in Villars 2 years ago were a few minutes out too.
Surprised me. In contrast the Tube ones are within a gnat's of
synchronised Casio time as told on m wrist. Once you go atomic on the
wrist watch, a bad comparison habit kicks off.

When I was still working at Uni Zürich, before I worked at PSI, I
used to go out to Brügg often, then take a bus to PSI for experiments and
meetings. The trains were supposed to leave every half hour, at xx28 and
xx58, but they were always late! Next timetable revision that was fixed
by re-scheduling them on the half-hour...

A ticket machine is self-contained. The CC cameras all link to a central
computer, on which you would hope the time is right. But there should be
electronic signs on the zone boundary though! As usual, all the technology
in the world is used to fine us, but a single LED per sign to help us is
considered not worth it.
