[ENG] 3.8. [DKSF 48.5 IU] How to Set up The Clock?
SETTING THE CLOCK MANUALLY
To set the clock manually, there is a need to go to the page «
» of a device web interface:
SETUP
In the section «
», it is possible to see and configure:
Embedded Clock (RTC)
Current Date and Time — is a field for viewing current time;
New Date and Time (14 digits, format DDMMYYYYHHMMSS with no spaces) – is a field for setting the new time manually.
After setting the clock, click the button «

TIME SYNCHRONIZATION WITH EXTERNAL NTP SERVERS
To configure synchronization with the external NTP servers, there is a need to go to the page «
» of a device web interface.
SETUP
This group of settings allows setting addresses of NTP-servers (servers of precise time), according to which a device will set and adjust its internal
clock. Overall, it is possible to set up to 2 NTP-servers. If the first NTP-serer is unavailable, then a device will attempt to synchronize its time with
the second one. It is possible to check the correctness of the adjustment by generating a time synchronization event and viewing this event in the
log at the page «
.
LOG»
In the section «
», there is a need to configure:
NTP Setup
NTP Server #1 — configuring the first NTP- server. It is acceptable to indicate or an IP-address either a domain name. On default:
.
NTP Server #2 — configuring the second NTP- server. It is acceptable to indicate or an IP-address either a domain name. On default: the address
is not specified.
Timezone — a configuration of a local timezone.
On default: UTC+03.00.
Daylight Saving Time (DST) — is a manual configuration of the daylight saving time. When a checkbox is checked, the internal clock of the device
shifts an hour ahead.
a checkbox is not checked.
On default:
You can use freely available NTP servers on the Internet as NTP servers. For example, one from

To use the NTP servers from the Internet, a device is going to have a gateway correctly configured, and a device should have the Internet
If an IP-address of an NTP-server is specified in the settings of the device, a device will attempt to get precise time and will synchronize its
internal clock with the precise time if successful. After the time synchronization, there will be two records in the log that represent the time
leap when the clock is reset to the precise time. If the time received at synchronization with an NTP-server is different from the time of the
internal clock for less than 5 minutes, the clock is not reset. Instead, the pace of internal clock is changed in the way to make the internal time
equal to the precise time received from the NTP-server. Thanks to this, there is no time leap in the list of events in the log, which simplifies
the analysis of the log.
