Hey, I just tried using org-shiftup on a timestamp, and got the following traceback. I'm using the Org package, and Emacs master from git.
Let me know if I should dig deeper! Debugger entered--Lisp error: (error "Invalid time zone specification" (nil nil nil)) encode-time(0 0 0 14 4 2016 (nil nil nil)) org-timestamp-change(1 nil updown) org-timestamp-up(1) funcall-interactively(org-timestamp-up 1) call-interactively(org-timestamp-up) org-shiftup(nil) funcall-interactively(org-shiftup nil) call-interactively(org-shiftup nil nil) command-execute(org-shiftup)
