The Pen Time Shifting functionality is only available for pens that belong to Local pages. The Time shift can be changed in the Edit Page dialog which can be accessed by the Edit Page in context menu in the Trend Folder side bar item, toolbar or menu.
After selecting a pen in the Page's Pen List in the Edit Page Dialog the time shift of the pen can be set using the two pen Time Shift fields on the dialog. The first time shift field determines the amount of the time shift and the second field determines the time units that the time shift is occurring in. The available time units are Hour, Minutes and Seconds.
By default all Pens have their Time Shift amount set to zero. If a positive time shift amount is entered for a pen then the pen is shifted forward in time. If a negative time shift is entered then the pen is shifted backwards in time.
