You might want to consider a photocell rather than a timeswitch.
Depends what you want to use the lights for. You can get ones
which fit in the light fitting. I added one of these to a light:

which only required drilling a hole on the top.

Alternatively just use a lamp with a built in photocell, provided
that the fitting allows it to "see" the outside light levels
properly

Photocell luminaires can also be controlled by a time clock. So
that, for example, they will be enabled between 06:00 and 09:00 and
16:00 and 23:30. This avoids having to adjust a time clock
throughout the year and only provides light when wanted.
