7.25 Time server (SNTP)
The time and date of the paperless recorder can be synchronized with a time server using the SNTP
protocol (Simple Network Time Protocol).
Device dialog box
Parameter
SNTP server
The server list is processed top down, in other words, the next time server on the list is only queried if
the previous server is unreachable. If no time server can be reached at the envisaged sync time, syn-
chronization is retried later (the repeat time starts at 1 minute and varies). After five unsuccessful at-
tempts, a "Time server error" message is added to the event list. After a wait, another attempt is made
to synchronize the time.
Time zone and daylight saving time
The SNTP server always provides the UTC time so that both the time zone and the time for switching to
daylight saving time are only defined by the device configuration (Configuration > Date and time).
