Section 3 — Maintenance and Troubleshooting
The Daylight Savings Time checkbox advances SNTP time by one hour, and is
available for use with SNTP servers that do not automatically correct for
this time change.
After making any SNTP changes, click on the Save button to enact the
changes.
System Parameters
The System Date is displayed on this screen, and on the service console
readout as part of the header for any error or event message.
When SNTP is not active, the System Date can be set manually by clicking on
the calendar icon, choosing a year, month, and day, and rebooting the SCB.
Note Encore SCB system date changes are not reflected immediately. The SCB
needs to be rebooted before the date changes will take effect.
You can reset the SCB with the Reboot button on the web page. If two SCBs
are running in redundant mode, both SCBs will need to have their system
dates set individually. For consistent log timestamps for both mirror and
master be sure to set both SCBs to the same date.
Frame Count Server
Operation of the Frame Count Server feature, available for use when VITC
or SNTP is not being used, is described in the separate Encore Configuration
Manual.
Note When using SNTP or VITC disable the Frame Count Server.
Logging Time and Date
The date and time data obtained from VITC/SNTP is used to log console
messages by all the applications running on the SCB. Other applications
which depend on VITC (like timed takes in CPS) are not affected by the
SNTP implementation. The time source used for logging has the following
priority: VITC, then SNTP, then Frame Count Server, and last System Up-
Time.
Table 16 shows in detail how time and date is applied to logging.
