2. Select the configuration source of the SNTP information in the SNTP Source choices.
3. If the SNTP source is Static , enter the following static IP information.
4. Enter a valid string in the SNTP Timezone field.
The format of the string is validated upon entry. Invalid entries are refused. The default value is:

A POSIX string is a set of standard operating system interfaces based on the UNIX operating
system. The format of the IEEE 1003.1 POSIX string is defined in the <bootp-dhcp-option-88.txt>
Internet draft as:
STDOFFSET[DST[OFFSET],[START[/TIME],END[/TIME]]]
Refer to the following sub-sections for explanations on each part of the string.
5. Set the synchronization information:
6. Click Submit if you do not need to set other parameters.
The current configuration file server information is displayed in the SNTP Info section.
STD / DST
Three or more characters for the standard (STD) or alternative daylight saving time (DST) time zone. Only STD
is mandatory. If DST is not supplied, the daylight saving time does not apply. Lower and upper case letters are
allowed. All characters are allowed except digits, leading colon (:), comma (,), minus (-), plus (+), and ASCII
NUL.
OFFSET
Difference between the GMT time and the local time. The offset has the format h[h][:m[m][:s[s]]] . If no offset is
supplied for DST, the alternative time is assumed to be one hour ahead of standard time. One or more digits
can be used; the value is always interpreted as a decimal number.
Table 25: Network Settings Configuration Sources
Source Description
Static You manually enter the value and it remains the same every time the Mediatrix 4104
restarts. Use the static configuration if you are not using a DHCP server or if you want
to bypass it.
DHCP The value is obtained at start-time by querying a DHCP server and using standard
DHCP fields or options. Using the DHCP configuration assumes that you have properly
set your DHCP server with the relevant information. See
“Chapter 8 - IP Address and
Network Configuration” on page 141 for more details.
Table 26: SNTP Static Address
Field Description
SNTP Host Static SNTP server IP address or domain name.
SNTP Port Static SNTP server IP port number.
Table 27: SNTP Synchronization Information
Field Description
SNTP Synchronisation Period Time interval (in minutes) between requests made to the
SNTP server. The result is used to synchronize the unit
with the time server.
SNTP Synchronisation Period on
Error Time interval (in minutes) between retries after an
unsuccessful attempt to reach the SNTP server.
