Fischi,
Sorry, I never used ProntoTimer so cannot help with this one.
I just checked his new site link as well and it is down. Did you try emailing him at the address on his profile on this site?
Here is the post with the link I tested.
[Link: remotecentral.com]With regard to setting the Pronto Time, there is no way to sync it except through download from PC. Anything you do from say weather.com would be a date/timebase change only. If your Pronto is 'losing time', I am curious if your battery drains quick as well because the only thing I could think of that might cause this would be something that is hogging the CPU.
