To verify when your template was last changed or to see other template settings/statistics, you can view the Template Settings.  You can find these on the screen where you select a template or when you have the template open.


On the screen where you select a template, first select your template.  With your Mapping Template selected, click on the drop down for the Template.  Then select "Template Settings" (shown below). 


With the template open, click on the drop down for the Template.  Then select "Template Settings" (shown below).



You can then see when the template was first created as well as when it was last changed.  You may also modify the template name if desired.
