In the Opportunities OWL the Created On field contains both Date and Time but when you open the Opportunity , Created On field displays only Date.Time is not displayed in Opportunities TI.
Reproducing the Issue
Go to Sales work center.
Go to Opportunities view.
Here under Created On column both Date and Time are displayed.
Open Opportunity 123(where 123 is Opportunity ID).
The Created On field in header section does not display Time.
This is the current system behavior.
