I got the analog Brinks timers from Wal Mart. I can send you a pic of them if you would like. Just make sure you get the one that allows for a grounded plug to be inserted. There are tabs every 30 minutes in the day, so they should cover your multiple lights-on periods. I believe they were either $5 or $6 in the store.
Whatever you do, do NOT get the digital Brinks timers. If the power gets cut, the whole timer resets itself, while the tabbed timers just freeze so you just have to spin them to the current time instead of having to reprogram the entire unit. I had a lengthy discussion with another member on this forum I believe about those vs. the standard tabbed timers, and after convincing him to go for the tabbed timer (he went through a handful of the digital timers), he didn't have any more problems that I am aware of.
