Configuring the Time Sync Module
In order to configure the Time Synchronization module go to Service tab,
Network Setup page, The Network Time section.
 Transport is used to set whether the Time Sync module selects the
source automatically or is manually forced to NTP or GPS source.
 The Main SNTP is used to configure the IP address of Primary NTP
server to be used.
 The Alternate SNTP is used to configure the IP address of secondary
NTP server to be used, in case primary is not available.
Using SNTP shows the current NTP server in use (Main, Alternate or Self if
no external NTP is used)
 Slew Mode configures the type of time slewing (adjustment) approach to
be used by the Time Sync module to compensate for time deviations and
network communication jitters. The default and preferred mode is
Automatic. When set to automatic, the slewing factor is according to
time source communication quality and you may only view the auto se-
lected slew factor and step time in the below fields.
You may further configure the slewing mode to manual and set the Slew
Factor and Step Time fields.
 Slew Factor is a percentage value between 0 to 100%, defining how
much to correct time in percentage towards the new GMT learned from
time source. 100% means full correction, or a step towards the received
time as is, and 0% means no change at all.
