Set time context for displayed attribute values

You use Set Time Context to specify a different time or time range for displayed attribute values. Changes to time context settings are applied to all attribute values in your AF database. After updating the time context, changes are shown on the Attributes tab of each element.

1. On the PI System Explorer toolbar, click .

   Alternatively, click Tools > Options and select the Time Context tab.

2. In the Set Time Context window, select one of the following options.

   Enter time values for an option directly, or click to select a date and time. You can also click to construct a time expression, such as *-1d.

   Option	Description
   Query Date Time	Displays the current setting for Query Date (defaults to Latest Available). You can specify a different date time setting for Query Date, to enable PI System Explorer to evaluate which versions of objects to retrieve from the PI AF database.
   Alternative Time	Displays the time context for data retrieval after applying the current Query Date setting. The default is the current time (*), but you can enter a new time context to use for displayed attribute values.
   Time Range	Enter Start and End times to specify a new time range to use for displayed attributed values that require a time range.

3. Optional. Click Set as Default to register the current settings as the default time context, or click Restore Default to restore the time context for Query Date Time to Latest Available.

4. Click Apply to see your changes and OK to keep them.

   The revised time context settings are displayed in the PI System Explorer title bar.
