We have loads!
A kitchen clock, and the one on the cooker (I don't count the microwave as it's never set anyway)
One in the conservatory
living room - has a pendulum
(easy to change as the hands are on the outside so you just move with a finger)
a digital clock radio on either side of the bed (I like to see the time when I wake in the night, so does T)
a little clock in the main bathroom
Jen has a big one on her bedroom wall
several watches (all mine, T doesn't wear one, but they're all wind-y ones)
our phones
the laptop
just remembered the central heating clock
(forgot to change it last night so the heating clicked on an hour earlier)
and the car - mine is dead easy to change but T's will be wrong for the next 6 months!
