With the Automatic Time (SNTP) option selected, the master network
server transmits time/date synchronization packets periodically to Strix
devices using the Strix Time Distribution (STD) protocol. Stack controllers
use STD to adjust their own time and date. Time and date information is
distributed in Greenwich Mean Time (GMT), allowing each device to
adjust for its own time zone. This allows Access/One Network to span
large geographic areas while maintaining time coherence.
If SNTP is configured at the network level, the master network server will
proxy the SNTP time requests on behalf of your entire Access/One
Network. The master network server effectively queries the SNTP server
periodically and adjusts its own time/date accordingly. STD time/date
information is then sent to all Strix devices on the network. If the master
network server fails (for any reason), all Strix devices will then query the
SNTP server individually.
• Manual Time
Choose this option if you want to set the date and time manually. To do
this, simply make your selections from the pull-down menus provided for
hour, minute, AM/PM, month and year, then click on the day of the
month on the calendar provided.
