TypeError: expecting datetime, int, long, float, or None; got <type 'unicode'>

[mx.tian@…]

also #13108

I found in the database "ticket_custom" table, the value of the field "due_date" is the character date "05-12-2016", if the number can be changed, such as "001489507200000000", so in order to solve it, I put all the characters date The replacement.

At this point the problem seems to have been resolved, but it is not true.

Now I want to report a new question, in the calendar click "New ticket with" 2017/02/28 "as the start date", give a new error.
