Hey ept8202,
My father has the same weather station, and he's got the same problems too...
Yes it seems that it doesn't do much with the local PC time, unless your Internet is completely disconnected I think.
The tool I was using is a freeware tool called "Fiddler", yes you can download and use it for free from http://www.fiddler2.com
What I did to overwrite the response was creating a simple html file which contained nothing else than the response "13385041 1338504189 22:43:09
May-31-2012" (so difference with actual response is in the second number). Don't include any html-tags or anything else, but your file needs extension ".html". You do need to monkey around with that value to make time/date be close to actual time and date,
as it otherwise still won't work.
Then in Fiddler you will see exactly what happens when you click "Update Forecast" in the WS application. Double-click on the "gettime2" URL to see the response received from server.
If you open the tab "AutoResponder", tag "Enable automatic response" and click "Add...", you can in the bottom of that tab where it says "Local flle ... to execute" browse to the html file you've created (select the last option "Find a file..." from the
dropdown). Click Save and try the Update Forecast again.
Good luck, and let me know what you find!
