Isn't this supposed to automatically update the clock to Daylight savings time? If not, How can i manually set the clock. Also, my unit doesn't switch into night mode when I turn on the lights. It only switches to night time mode at 7PM, what can be wrong. I have double checked everything and everything is connected properly.

Already being discussed over here:

looks like someone forgot to put the winCE DST patches in the build.
