Synchronizing the System Time in the
Network
 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.
