Well, after getting the Dectalk PC2 driver working with Speakup, I never expected this. When I'm actively using the Dectalk PC, my clock starts wondering into the sunset. For example, by the end of the day yesterday, it was about 3 minutes slow. Today, as a test, I set it and then ran a loop of having ntpdate query the time from time.nist.gov every 60 seconds. I had it set to query without setting the clock, so I could see how far it was drifting. The offsets over just 3 minutes are alarming! 6.317230 seconds slow in minute one, 11.267927 seconds slow after 2 minutes, 16.887154 seconds slow after minute 3, and so on. If I leave the computer idle, with ntpd running to constantly adjust the time, it becomes stable, so it's clearly something that the Dectalk PC is doing. Has anybody else had this problem? For that matter, is anybody even using the Dectalk PC driver besides me?
