NetWare Directory Services uses time stamps to
• Establish the order of events (such as object creation and partition replication)
• Record “real world” time values
• Set expiration dates
Time stamps are especially important when NetWare Directory Services
partitions are replicated and need to be concurrent with one another.
Replication allows partition updates to originate from many locations. As
various users update the partition’s replicas, some updates will inevitably
pertain to the same data.
For example, a user might delete an object and then recreate it. But without a
method of recording the order of these events, the Directory could try to
create the object and then delete it.
Time stamps allow the Directory to reproduce the “real world” order of
events.
By default NetWare Services, using the NetWare Time Synch daemon
(ntsd), handles time synchronization for the HP-UX system. If your HP-UX
system is time synchronizing by another method, such as Network Time
Protocol (NTP), you should disable the NetWare Services synchronization
by configuring it as a Reference Time server (nwcm parameter ts_type set to
“reference”).
You can change time synchronization parameters with the graphical
NetWare Setup” utility or with nwcm.
Time server types
NetWare servers can be designated as Single Reference, Primary, Reference,
or Secondary.
If a NetWare Services server contains the root of the NetWare Directory
Services tree, the server defaults to a Single Reference time server.
If a NetWare Services server does not contain the root of the NetWare
Directory tree, the server defaults to a Secondary time server.
Each time server type performs a particular time synchronization function:
• Single Reference time server. Provides time to Secondary time servers and to
