The clock has always run slow on V/AT 2.3 running on our 5-star system. I have tuned clocktic with no real change. I decided it was time to do some analysis. Here is what a found. The clock looses minutes. In other words, if I boot and set the clock, some time later it will be 1 minute slow or 2 minutes slow or whatever. The seconds are always correct. Also, the number of minutes lost is not really a function of time since boot; it could loose 1 minute in the first 10 and then not loose another for 3 hours. To me, it sounds like a lost interrupt. The 5-star is a strange beast which could exacerbate the problem. The CPU is on a card slot so all memory access goes over the buss. The only thing that plugs directly into the CPU card is the keyboard. -- Phil uunet!pilchuck!ssc!fyl
