About the NTP Server
The NTP server is a remote server with which the VCS
synchronizes in order to ensure its time setting is accurate. The
NTP server provides the VCS with UTC time.
Accurate timestamps play an important part in authentication,
helping to guard against replay attacks. For this reason, if you
are using authentication, both the VCS and the endpoints must
use an NTP server to synchronize their system time.
Traversal clients must always authenticate with traversal
servers, even if the server’s authentication mode is off (this
setting applies to endpoint authentication only). Therefore
in order for a traversal client and traversal server to connect
to each other, both must be configured with details of an NTP
server.
About the Time Zone
The NTP server provides the VCS with UTC time. You can
also determine the local time to be used on your system by
configuring the
Time Zone.
This takes the UTC time and offsets
it by the number of hours specified by the selected time zone to
make the local time.
The local time is used throughout the web UI and to set the
timestamp that appears at the start of each line in the Event
Log.
