reset to its default time. (Please check the applicable battery backup period mentioned in RTC
section).
•
If GPS Master Clock Model MC-1-M was Lock for once after being Power UP, GPS Master Clock
Model MC-1-M will retain accurate NTP output in holdover conditions (according to its local clock
ppm accuracy).
•
NTP Client time accuracy depends on multiple factors such as Client local clock frequency ppm,
network load and congestion, type of clock synchronization algorithm in NTP Client devices other
than Unix/Linux PC, hierarchical arrangement of NTP servers and NTP clients in network and
GPS Master Clock Model MC-1-M NTP Clock output accuracy during holdover conditions (when
device is Unlock as per ppm of internal clock crystal) etc.
•
GPS Master Clock Model MC-1-M NTP output is compliant with NTP version 4 NTP request but
do not support various authentication schemes as per NTPv4.
