Unit Configuration Basics
Conflicting Time Zones
A Multi-Media unit’s time zone can be changed without the knowledge of a View operator.
It can be done at the unit, using LocalView, or through another Multi-Media database (Multi
db). The View operator’s next attempt to access the site is interrupted by a message (shown
in
Figure 4-3 ).
The message also appears for areas within a time zone that have different rules for daylight
savings time. For example:
Indiana (East)
in the Eastern time zone (GMT-5:00) differs
from
Eastern Time (US Canada)
, also GMT-5:00. To respond to a notification of
conflicting time zones, select the time zone that indicates where the Multi-Media unit is
installed and then click OK.

Setting the Clock Automatically with SNTP
See your IT Administrator to find out if a Simple Network Time Protocol (SNTP) server is in
use. Multi-Media units on a LAN can benefit from the automatic setting. It is accurate to
within a fraction of a second.
1. Obtain the IP address of an SNTP server. You have the option of also obtaining the
address of an alternate server.
2. Using View, select a unit whose clock needs to be set.
3. Start a Maintenance Session .
4. Click the Time tab.
5. If Automatic is not selected, click it. The Time tab appears as in Figure 4-2 .
6. Select the Primary SNTP Server box and enter the IP address of the SNTP server
obtained in
step 1 . You have the option of indicating an alternate in the Alternate
SNTP Server box.
7. Click Refresh. The Multi-Media unit contacts the SNTP server and synchronizes the
Multi clock to the SNTP time.
c
Display can be changed for a session’s duration to LTZ (the local time zone set on
your PC), RTZ (a camera’s remote time zone) or to UTC (universal time zone). See
