7.1 Entering the time
If no reference clock is available, you have the option of entering the system
time in a device and then using it like a reference clock.
(see on page 94
„Configuring SNTP“) .
Note: When setting the time in zones with summer and winter times, make
an adjustment for the local offset. The device can also get the SNTP server
IP address and the local offset from a DHCP server.
Select the Time dialog.
With this dialog you can enter time-related settings independently of the
time synchronization protocol selected.
X The “IEEE 1588 time” displays the time determined using PTP.
The “SNTP time” displays the time with reference to Universal Time
Coordinated (UTC).
The display is the same worldwide. Local time differences are not
taken into account.
X The “System time” uses the “IEEE 1588 / SNTP time”, allowing for
the local time difference from “IEEE 1588 / SNTP time”.
“System time” = “IEEE 1588 / SNTP time” + “Local offset”.
X “Time source” displays the source of the following time data. The
device automatically selects the source with the greatest accuracy.
With “Set time from PC”, the device takes the PC time as the system
time and calculates the IEEE 1588 / SNTP time using the local time
difference.
“IEEE 1588 / SNTP time” = “System time” - “Local offset”
The “Local Offset” is for displaying/entering the time difference
between the local time and the “IEEE 1588 / SNTP time”.
With “Set offset from PC”, the agent determines the time zone on
your PC and uses it to calculate the local time difference.
