The time filter lets you filter events in the TrueSight console, based on when they occurred.
Predefined time periods: You can select a time period from the list and events that have occurred during the selected time period are displayed.
Custom time period: You can create a custom time period for which to filter events.
To change the date and time format, see Setting user preferences.
Custom time periods that you create are not available after you log off the TrueSight console.
