The Network Time Protocol (NTP) provides a means to synchronize
time and coordinate time distribution throughout a TCP/IP
network. NTP aims to provide accurate and dependable timekeeping
for hosts on TCP/IP networks.
NTP provides synchronization traceable to clocks of high absolute
accuracy and avoids synchronization to clocks keeping incorrect
time.
Configuring and managing NTP on your OpenVMS host involves the
following tasks:
o Determining which network hosts to use for synchronization
o Creating and populating the NTP configuration file with the
list of participating hosts
o Defining a time-zone differential (offset) logical name
o Using the NTPDATE program to set the local date and time
o Using the NTPTRACE utility to determine the source from which
an NTP server obtains its time
o Using the NTPDC query program to make runtime changes to NTP
