When I call either active or inactive timestamps and enter the current date from the keyboard, i.e. 2/10, rather than simply pressing enter the result is <2016-02-10 Wed> or [2016-02-10 Wed], i.e. the year is already advanced. If I enter any date in the rest of the month in same manner such as 2/28 same result, <2016-02-28 Sun> or [2016-02-28 Sun] the year and day of the week are advanced. The behavior disappears when I go to the next month.

GNU Emacs 24.4.1 (i586-pc-linux-gnu, GTK+ Version 3.14.5) of 2014-12-19 on brahms, modified by Debian
Org-mode version 8.3beta (release_8.3beta-806-g0be849 @ /usr/share/emacs/site-lisp/org-mode/lisp/)

Is it intended that only the shift + arrow keys be used during the current month?
