Configuring Clock Synchronization
The Clock Synchronization feature allows you to synchronize the X Series unit’s internal real
time clock to an external reference time source using Simple Network Time Protocol (SNTP).
SNTP servers provide Coordinated Universal Time (UTC) which is the primary time standard
by which the world regulates clocks and time. In order to convert this standard time to the local
time, the X Series allows you to configure a timezone offset. A timezone offset is the difference
in hours and quarter-hours from UTC time for a particular locale. The timezone offset is a
positive number if the local timezone is ahead of UTC and a negative number if it is behind.
Additionally, for locations that observe Daylight Saving Time, the X Series provides a setting
that, when set to On, immediately applies an additional 1-hour positive offset from UTC. The
supervisor sets the initial value and the operator may subsequently toggle Daylight Saving
Time on or off as necessary on the Set Date and Time screen (see “Setting the Date and Time”
on page 2-20).
When Clock Sync is enabled and a network connection is available, the X Series unit
automatically acquires a reference time from the SNTP server and converts the reference time
to local time. The X-Series will acquire a reference time from the SNTP server if no reference
time has been acquired since the unit was powered on or the Clock Sync configuration settings
have been changed. To ensure that the real time clock never changes during patient treatments,
the X Series will make adjustments to its clock, if necessary, after the unit has been off for at
least two minutes and prior to the start of a new case.
When Clock Sync is enabled, you can see the time of the last synchronization on the Set Date
and Time screen. The X Series also provides the message
Clock Synchronization Failed
when an
attempt at synchronization fails after the SNTP server settings have changed or if there has
been no successful synchronization for 1 week or more. See “Setting the Date and Time” on
page 2-20 for information on using the Set Date and Time screen.
