Time Zones 
An inevitable consequence of allowing the RTM device user interface to be 
accessed across networks is the crossing of time zones. Various features of the user 
interface display timing information, including the Log files. You need to know the 
time source being used to record events. Also, when scheduling the loading of 
configuration files, time zones must be taken into account (see Scheduling
page 3-91). 
Figure 2-8 shows a typical setup in which an MTM400 is located in Denver and is 
monitored from Portland. In local time, Portland is one hour behind Denver. In this 
example Universal Coordinated Time (UTC) is 10 p.m. Therefore the local times 
in Portland and Denver are 2 p.m. and 3 p.m. respectively. 
Denver
Local Time = 3 p.m.
UTC = 10 p.m.
UTC/Local Offset = -420 minutes
Portland
Local Time = 2 p.m.
UTC = 10 p.m.
UTC/Local Offset = -480 minutes
UTC = 10 p.m.

Figure 2-8: Time zones - illustration 
The MTM400 user interface allows you to coordinate times of the system elements 
and to choose the local reference time zone; UTC, local time at the client PC or 
local time at the RTM device. All times are calculated with respect to Universal 
Coordinated Time. (See Device Configuration - Set Time, page 3-9.)
