• Adjust the system clocks.
• Change DTS attributes for varying WAN conditions.
• Modify the system configuration when the network environment changes.

5.5.1 Managing the Distributed Time Service
You can use the dcecp program to create and enable DTS. Once this is done, you can
perform routine management tasks, such as enhancing performance, reconfiguring the
network, and changing local time.
Several commands and characteristics modify and improve the performance of your
network. The dts modify command changes the values of many of these characteristics.
The dts show command displays the values of characteristics at any time. The following
are some of the tasks you can accomplish using the DTS commands and the
characteristics of DTS that can be set:
• Display or change the number of servers that must supply time values to the system
before DTS can synchronize the system clock.
• Display or change the inaccuracy limit that forces the system to synchronize in order
to bring the inaccuracy back to an acceptable level.
• Display or change the interval at which you want clock synchronization to occur.
• Display or change the reaction to a faulty system clock.
• Display or change the settings that indicate how often to query servers.
Refer to the for more information on these and the following tasks:
• Creating and enabling DTS.
• Assigning the courier role to servers to facilitate communications to other parts of
your network.
• Matching the epoch number for servers that you add to your network after the initial
configuration. An epoch number is an identifier that a server appends to the time
values it sends to other servers. Servers only use time values from other servers with
whom they share epoch numbers.
• Advertising DTS servers to CDS, thereby registering them as objects in the
namespace.
5.5.2 Modifying System Time
Sometimes you need to modify the system time. You can update time to match the
international time standard, Coordinated Universal Time (UTC), from a source such as
telephone, radio, satellite, or another external referencer, if your network does not use
