Incorrect date format in en_CA.UTF-8 locale

[Paul Natsuo Kishimoto]

Bug #214730 resulted in an *incorrect* change of d_fmt in the Canadian English/UTF-8 locale.

The date format was "%d/%m/%y" (04/02/10), then it was changed to "%y-%m-%d" (10-02-04). Even though the bug thread cited several references to Canadian standard CSA Z234.5:1989, which is identical to ISO 8601, the second format is ALSO incorrect.

From http://en.wikipedia.org/wiki/ISO_8601#Years:

"ISO 8601 prescribes, as a minimum, a four-digit year [YYYY] to avoid the year 2000 problem."

From the FAQ page at the Government of Canada website (http://www.nrc-cnrc.gc.ca/eng/ibp/inms/about/faq-time.html#Q8) that was linked from the other issue:

"The recommended full format is of the form 2001-12-31 23:59:28.73 UTC."

The correct format is "%Y-%m-%d" (2010-02-04).

In the file debian/patches/ubuntu-en_CA-dateformat.patch, the lines:

-d_fmt "<U0025><U0064><U002F><U0025><U006D><U002F><U0025><U0079>"
+d_fmt "<U0025><U0079><U002D><U0025><U006D><U002D><U0025><U0064>"

...should instead be:

-d_fmt "<U0025><U0064><U002F><U0025><U006D><U002F><U0025><U0079>"
+d_fmt "<U0025><U0059><U002D><U0025><U006D><U002D><U0025><U0064>"

Since still in 11.04 Natty, I reported the bug to glibc and submitted a patch.
