3. DST Tab (cont)
a. Daylight Saving Time – This is used to set the DST to AUTO, OFF, or CUSTOM. The AUTO selection is the
standard DST for the United States.
Note: Not all time zone selections will allow for changing the DST to AUTO or OFF. For example, if USCT – USA
Central is selected for the time zone, the DST cannot be set to OFF. In this example DST=OFF can be
done by selecting UTC-6 for the time zone and selecting the DST to OFF. Reference Appendix B for a list of
all available DST configurations.
b. Custom Daylight Savings – This is used to select a custom DST date and time. The Daylight Saving Time
must be set to CUSTOM for these fields to be editable.
4. Network Tab
a. DHCP – This checkbox enables Dynamic Host Configuration Protocol (DHCP) on the selected network clocks.
b. IP Address – The IP address may be set to a static IP address if one clock is selected. The DHCP checkbox
must be unchecked for this field to be enabled. The IP address fields cannot be changed if multiple clocks
are selected.
c. Subnet Mask – The Subnet mask may be configured if the DHCP checkbox is unchecked.
d. Gateway – The Gateway may be configured if the DHCP checkbox is unchecked.
e. DNS Servers – The DNS servers may be configured if the DHCP checkbox is unchecked.
f. SNTP Servers – This is a list of SNTP servers from which the network clock will receive time. The selected
server will be attempted first. If the server fails to provide a valid time the list is traversed until a valid time is
received. This list may be user defined. A list of verified NIST time servers is available in Appendix A.
