Intermatic timer DT620CL,
Verified Purchase(What's this?)
This review is from: Intermatic DT620CL 15 Amp Indoor Astronomic Digital Timer (Tools & Home Improvement)
This timer does it all. It tracks the time zone the user is in, the day of the month, etc. It can calculate the sunrise and sunset accordingly so you do not have to change your program as the days get longer and shorter. It has a resonable price. It has battery backup so a power outage will not erase your program. A very impressive product.
