Help!! How do I set my light timer!?

From the description, you set the pointer to the current time. Then around the edge of the dial are tabs which you can pull up or push down . Tabs that are pulled up represent time when the light is OFF, tabs which are pushed down represent time when the light is ON. Make sure the switch on the light is ON before you plug the light into the timer. (you checked this, right? That the light goes ON when plugged into a live socket and you do not have a burned out bulb?) Then turn the pointer slowly in the direction indicated. You should see the light turn on and off as the tabs move past the stationary pointer. Continue to turn until once again, the pointer is set to the correct time. I leave my timer set to standard time because sunrise and sunset does not change an hour (as the clocks do) during daylight saving time is in effect and my times stay in sync with sunrise and sunset. Why turn on the light at noon? I can understand 11PM because it is dark outside, but why turn on the light during the daytime? Why not turn on the light a little later, closer to sundown? By the way, the red switch is likely an override. Some have 2 positions, auto and on, and some have three positions, off, auto and on. ON and OFF force the timer to stay that way and the lights do not cycle based on the tab settings. The lights cycle ONLY when the switch is in AUTO.
