SYSTEM MENU – TIME/DATE
SMΩRF has built-in Real Time Clock (RTC) to allow to mark backups with date signature as well as to provide
UTC and local time/date for screen saver. Special feature is that RTC can be synchronized by internet clock
reference and keep time in the SMΩRF updated and very accurate. This menu allows to set time and date, its
format as well as synchronization parameters.
CONTROLS:
1.
UTC
Sets UTC time.
2.
WEB SYNCHRO
Enables synchronization of the
internal RTC with internet clock
reference. Next is shown real time
status of the synchronization. When
WEB synchronization is enabled, time
is updated once an hour.
Normally you should see just DOWN and SYNC state, but there are more states describing current
status which may help for troubleshooting:
DOWN – synchronization is turned off, or there is no internet connectivity.
WAIT RESPONSE – RTC is waiting for response from the NTP server. This happens when the NTP
server is busy or not responding.
WAIT FOR DNS – RTC is waiting for response from the DNS server. This happens when the DNS
server cannot translate NTP server's name to the IP address, usually by miss-
typed NTP server name.
RETRY – RTC tries to reconnect to the NTP server.
SYNC – synchronized, next to the status is shown time/date of the last synchronization.
3. NTP SERVER
Sets address of the time server, default is “pool.ntp.org”
4. TIME FORMAT
Sets time format to 12 or 24 hours.
5.
LOCAL TIME
Set local time shift to the UTC time. Next to the shift, local time is shown in format according to settings.
6.
DAYLIGHT
Enables/disables daylight saving shift for the local time.
7.
DATE
Sets DATE. Next to it, local date is shown in format according to settings.
8. DATE FORMAT
Allows to set DATE format to DD-MM-YYYY or MM-DD-YYYY format.
9.
BATTERY
Shows status of internal battery used for RTC powering. Battery should last for many years and is
replaceable (CR2032) when needed (when drops below 2.75V).
