When I used this shortcut yesterday, December 31, 2017, I get 31/12/17. It seems date formats are generally very flexible in Tinderbox. I have not been able to find where I can change the format used by the shortcut.
I confirmed that my OS X Preferences are set to display mm/dd/yy. I often use the system attribute Created as a Key Attribute in my work. It is displaying consistently with the format set in OS X Preferences, mm/dd/yy.
Am I missing sometime or is this a feature request? If the format were set to match that used in my system prefs that would be fine. I have no need to be able to change the format used by the shortcut.
