Ticket date problem (TracJSGanttChart related?)

[Joost Kraaijeveld]

Hi

I am trying to convince Trac to use the Dutch version of date and time
notation ( hh:mm:ss dd-mm-yyyy , ISO 8601). While experimenting I
managed to introduce an error. I created a ticket and now I get the
following errors, depending on the actual date notation used of course:

Ticket 4 has an invalid userstart value, "11-5-2013". It should match
the format "%Y-%m-%d".
Ticket 4 has an invalid userstart value, "11-5-13". It should match the
format "%Y-%m-%d".
Ticket 4 has an invalid userstart value, "11-05-13". It should match the
format "%Y-%m-%d".

Changing the date to "2013-05-13" works OK, but that is not what I
want.

The only entry in the Trac.ini that mentions "date_format = %Y-%m-%d" is
[TracPM], which is JSGanttChart related I believe?. Changing that to
another format (e.g. to "date_format = dd/mm/yyyy" or "date_format =
dd-mm-yyyy" or "date_format = %d-%m-%Y") did not change the error
message part "It should match the format "%Y-%m-%d".

Is it possible to convince Trac to use Dutch time/date notation
*throughout* the whole interface? I.e. tickets, timelines, roadmaps?

TIA
