Ok first things first. Open your settings on the sigma and get to the clock settings click set with the lower left and the hours should blink. The upper left buttons will change the hour setting from one to 24 then set ok and the minutes should blink then set them and press set ok I think that might work. There is a demo on the Sigma website which I'm sure you saw but I been messing around with that thing for a few minutes. Try it and see if it works. I've been here since 1978 and I like it a lot but if you can't handle 9 months of grey skies and rain the its not for you. Its beautiful when its sunny and the mountains are out but boy by now since we have had an extremely crummy spring I'm about to go nuts. Portland is generally warmer the sunnier than the Seattle area but it can be gloomy there to. Portland is a lot more bike friendly than Seattle or Tacoma also
