32-4 System Maintenance
32.3 Time and Date Setting
The Real Time Chip (RTC) keeps track of the time and date (not available on all models). There
is also a software mechanism to set the time manually or get the current time and date from an
external server when you turn on your HomeSafe. Menu 24.10 allows you to update the time and
date settings of your HomeSafe. The real time is then displayed in the HomeSafe error logs and
firewall logs.
Select menu 24 in the main menu to open Menu 24 - System Maintenance, as shown next.
Figure 32-6 Menu 24: System Maintenance
Enter 10 to go to Menu 24.10 - System Maintenance - Time and Date Setting to update the
time and date settings of your HomeSafe as shown in the following screen.

Table 32-3 Time and Date Setting Fields
FIELD DESCRIPTION
Enter the time service protocol that your timeserver sends when you turn on the
HomeSafe. Not all timeservers support all protocols, so you may have to check with
your ISP/network administrator or use trial and error to find a protocol that works. The
main differences between them are the format.
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC-868) format displays a 4-byte integer giving the total number of seconds
since 1970/1/1 at 0:0:0.
NTP (RFC-1305) the default, is similar to Time (RFC-868).
Time Protocol
None enter the time manually.
Time Server
Address Enter the IP address or domain name of your timeserver. Check with your
ISP/network administrator if you are unsure of this information. The default is
tick.stdtime.gov.tw
Current Time This field displays an updated time only when you reenter this menu.
New Time Enter the new time in hour, minute and second format.
Current Date This field displays an updated date only when you reenter this menu.
New Date Enter the new date in year, month and day format.
