8.3.13 SNTP (Simple Network Time Protocol)
The SNTP client allows the PTP 400 Series Bridge to obtain accurate date and time updates
from a networked timeserver. The resultant time information is used by the SNMP, web page
and System Reboot tasks.
SNTP State: The SNTP state attribute controls the creation of the SNTP features.
When enabled the following options are available:
SNTP IP Address: The IP address of the networked SNTP server.
SNTP Port Number: The port number of the networked SNTP server. By convention
the default value for the port number is 123.
SNTP Poll Interval: The period at which the SNTP client polls the server for time
correction updates. Default 1 hour. If for any reason an SNTP poll fails the client will
automatically perform 3 retries before waiting for the user defined poll period.
SNTP Sync: Displays whether the SNTP client is in sync with the specified SNTP
server.
SNTP Last Sync: The timestamp of the last time the SNTP client successfully
synchronized with the SNTP server.
System Clock: Displays the current system clock.
SNTP Time Zone: The SNTP time zone is a fixed offset from GMT that is added to
the correct time to allow the expression of time in all geographic time zones.
When disabled the following options are available:
Set Time: Field used to set the current time (HH:MM:SS).
Set Date: Pull down menus to set the current date.
Time Zone: The time zone is a fixed offset from GMT that is added to the correct
time to allow the expression of time in all geographic time zones.
Daylight Saving: Enables daylight saving by adding one hour to the displayed system clock
timestamp.
