Workstation h2pslws0 time of day clock had drifted 21 seconds fast. This results in not being able to use DTT to collect test point data. Found that the NTP server could not respond to ntpd because h2pslws0 is on a different network. Set up NTP server to use a gateway that can reach the 10.205 network, then restarted ntpd on the workstation.
