Managing Network Time Synchronization
Procedure
1 HP recommends that you use SAM to set the bindery context and most time
synchronization parameters. Use the nwcm command to set the other parameters.
The nwcm command is described in the Utilities Reference.
2 Set the following variables as appropriate.
Basic. This category shows the most commonly changed time synchronization
variables.
Time Server Type. This variable specifies how the server synchronizes time
(set by dsinstall): Single, Reference, Primary, or Secondary.
Enable Time Service Advertising? This variable controls time source
advertising. “Yes” means Single Reference, Reference, and Primary time
servers advertise; Secondary time servers do not advertise. “No” means time
servers do not advertise. If it is a time source for other servers, you must add
its time to those servers’ lists of time sources. The default is Yes.
We recommend that all servers be configured the same (“Yes” or “No”) for
this variable to be effective.
Directory Tree Mode? This variable controls whether the server
synchronizes time with services in its tree and with all servers on the
network.
This variable has no effect if the “Use Only Configured Sources” variable is
set to “Yes.”
When “Use Only Configured Sources” is set to “No,” this variable works as
follows:
• “Yes” means the server synchronizes only with services in the Directory
tree.
• “No” means the server attempts to synchronize with any time source on
the network. With this configuration, make sure any nonproduction
servers do not advertise time services.
Time Sources. This variable contains the list of time sources this server
contacts to determine network time. When the first time source is contacted,
the search stops.
Use Only Configured Sources? This variable determines which time sources
the server listens to. “Yes” means servers only listen to the sources in the
configured sources list (“Time Sources”). “No” means the server first
attempts to contact a server listed in the configured sources list; if
