Where, when, and with what time standard the HS/FS is synchronised, is set here. In addition, the HS/FS date and time can be sent to the KNX.
If there is an active connection to the Internet, the date and time of the HS/FS can be synchronised daily with an NTP server (NTP: Network Time Protocol). In addition, automatic synchronisation with an NTP server is performed on startup. Both the date and the time are synchronised.
Alternatively, the HS/FS date and time can be received from the KNX.
Important: The HS/FS automatically switches over from summer to winter time. A connection to an NTP server is not required for this purpose! The automatic changeover to winter time only takes place if the HS/FS is switched on continuously on the last Sunday in October from 01:59 a.m. to 03:01 a.m.! In addition, it is also possible to set a time zone.
Central European summer time always begins on the last Sunday in March at 2 a.m. Central European Time (CET). At the point in time of the start of summer time, the hours setting is advanced by one hour from 2 a.m. to 3 a.m. Central European summer time always ends on the last Sunday in October at 3 a.m. Central European Time (CET). At the end of summer time, the hours setting is set back by one hour from 3 a.m. to 2 a.m. The hour from 2 a.m. to 3 a.m. appears twice.
If the specified time synchronisation options are not available, it is possible to set the time with the Date and time mask of the HS/FS. The mask can be created in the HS/FS interface and changed by the user.

1.Synchronise with NTP server
Yes: Date and time of the HS/FS are synchronised via an NTP server on the Internet.
Address of the NTP server
This server is used for synchronisation. If a server cannot be reached, the alternative NTP server is used.
Note
The following list of NTP servers was tested with the HS/FS. Please note that the specified NTP servers may not be reachable temporarily. Enter 2 different servers in this mask if possible. No guarantee shall be assumed for the correctness of the addresses!
The TimeServers return the current time as GMT +1:
ptbtime1.ptb.de
ntps1-0.cs.tu-berlin.de
ntp1.fau.de
ptbtime1.ptb.de
ntps1-0.cs.tu-berlin.de
ntp1.fau.de
Alternative NTP server
See NTP servers
2.Receive date/time from KNX
Yes: HS/FS can be synchronised by a clock, e.g. DCF 77.
Communication object for date
The date is received from this communication object. A 3-byte KNX data format is expected.
Communication object for time
The time is received from this communication object. A 3-byte KNX data format is expected.
3.Send date/time to KNX
Yes: The HS/FS can send date and time cyclically to the KNX. All devices that understand the 3-byte KNX data format can be synchronised with it.
Note
The day of week is also sent together with the date.
Communication object for date
The date is sent to this communication object. A 3-byte KNX data format is expected.
Communication object for time
The time is sent to this communication object. A 3-byte KNX data format is expected.
Send cyclically
The data is sent to the KNX at this interval. In addition, the option Sending only possible via commands is also available.
