Time Editor

The Time Editor allows you to configure the time range for which you want to view data within a chart. By entering the Start and End times, you select the time range of data that is fetched from Historian and is available.

The Time Editor displays the time zone as either Local or UTC. Your system administrator can configure the time zone with the System Config tab, which is accessible by clicking the Admin drop-down menu and then selecting Administration.

The default End time is NOW (current time) and the Start time is NOW minus 1 hour.

Note:
  • The default Start time for the first chart you create is the previous hour (1-hour relative time default).
  • The clock is not active when you leave the Analysis tab open and time elapses until you start creating charts. For example, if you open the Analysis tab and walk away from your computer for an hour and then create a chart, your chart will be "Stale" as the time period for the fetch is defined by the Start and End time in the editor. This becomes apparent if you also create a Value Card or Current Value Table with the same tag. The values and timestamps will be off an hour.
