 0=have background color specified under
Elements.
Start Time/End Time
Default start and end time range (must be a valid
FactoryTalk Historian string).
UpdateTimeRange
Maximum time period, in seconds, to support
updates. The default is 604,800 seconds, equal to 7
days. If the time range is greater than this value, the
trend does not update automatically even when the
end time is '*'. Note that the maximum update range
is different from the update rate, which is the
frequency with which the computer displays new data
from the server, typically every 5 seconds.
