Why, except as a backup, and as a backup you can use a higher stratum clock, making sure that it is not getting its time from you even indirectly (you do not want loops). >This is very much a hobby project for me, not a serious thing though I am >perfectly willing to add to the public ntp server list but I don't think >this rig would qualify to peer with the nist or usno servers or any such >thing so I'm hoping stratum 1 peering isn't necessary. Use pool.ntp.org as a backup for your gps. You will only get 100s of usec to ms accuracy from those backups, but then they are backups. YOu could also buy another 5 GPS18s to use as backup if you really wanted to make sure you get usec time at all times. >Thanks, >Shane _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
