You require a timeswitch with a changeoever contact rather than a
simple on-off. You may find that your existing timeswitch already has
this facility.

The terminals will be marked :-
NC for Normally closed.
NO for Normally open
and C for Common.

C would be a Live feed.
NO would be light A
NC would be light B

Or of course you could reverse A and B

You could also do it with a changeover relay... (i.e. DPDT)
