With this dialog you can enter time-related settings independently of the time
synchronization protocol selected.
The “System Time (UTC)” displays the time with reference to Universal
Time Coordinated.
The time displayed is the same worldwide. Local time differences are not
taken into account.
The ”system time” uses "System Time (UTC)", allowing for the local time
difference from "System Time (UTC)".
“System time” = “System Time (UTC)” + “local offset”.
“Time source” displays the source of the following time data. The device
automatically selects the source with the greatest accuracy.
Possible sources are: local, ptp and sntp. The source is initially
local.
If PTP is activated and the device receives a valid PTP frame, it sets its
time source to ptp. If SNTP is activated and if the device receives a valid
SNTP packet, the device sets its time source to sntp. The device gives
the PTP time source priority over SNTP
With “Set time from PC”, the device takes the PC time as the system time
and calculates the system time (UTC) using the local time difference.
“System Time (UTC)” = “system time” - “local offset”
The “local offset” is for displaying/entering the time difference between the
local time and the “System Time (UTC)”.
With ”Set offset from PC“, the device determines the time zone on your
PC and uses it to calculate the local time difference.
Note: When setting the time in zones with summer and winter times, make
an adjustment for the local offset, if applicable. The device can also get the
SNTP server IP address and the local offset from a DHCP server.
