network and your server is not synchronizing within its Directory tree.

• You want to control the sources your server uses for time synchronization.

• You want to reduce SAP traffic by turning off time service advertising.

For more information on restricting valid time sources, see the following

variables in SAM:

• Enable Time Service Advertising?

• Use Only Configured Sources?

• Time Sources

• Directory Tree Mode

See “Creating a Custom Time Source Conﬁguration” below in this chapter

for more information.

Polling Intervals

During a polling interval, time servers exchange a conﬁgurable number of

packets which they use to compare their current time with the responding

server's time. The default is to send three packets, enough to adjust for

network ﬂuctuations but not so many as to ﬂood the network with time

synchronization packets.

A server does not always poll at the same interval. When a server is not

synchronized with the network, the server polls according to the short

interval value (the default is 10 seconds) until its time is synchronized with

the network. Once time synchronization is established, the server gradually

increases its polling interval until it matches the polling interval value (the

default is 10 minutes).

For more information on conﬁguring polling and its intervals, see the

following variables in SAM:

• Polling Count

• Short Interval
