Hello, recently I tried building a microsecond precision timeserver using a gps-device with pps signal.
The gps-data is transmitted via usb, the pps signal via the rs232 carrier detect line. I tried several drivers and they all worked, but I had to figure that obviously my mainboard (via epia en12000EG) has terrible jitter. - unusable! To solve the problem I think about simply setting the time every n seconds according to the collected gps time and the pps-signal. My system will run off for far less than a microsecond in an interval of let's say, 20 seconds or so. Like this I would implement a constantly jumping time, but the amount of jumps would be extremely small. Since I learned that timekeeping is a very complex topic, I thought, I'd better ask on this list, before I build something troublesome without even knowing.. What do you think?
