Time and Time Ranges
The following example is a trend displaying data through the current time.
The right border of the trend is dotted, signifying current time, rather than
solid, signifying a specific time in the past or future. The value scale may
also change if the trend is formatted to have Autorange scaling.
Depending on your configuration, the time zone represented on a display is
either the client machine time or the time relative to the Historian Server.
For details, see Change Time Zone (page 26).
Time Range Formats
All trends have beginning and ending time values that define the span of
time for which data is plotted. These values can be expressed in absolute or
relative time.
Other symbols on a display are also affected by time ranges.
