            Bug ID: 17426
           Summary: date format not set for en_IN
           Product: glibc
           Version: 2.20
            Status: NEW
          Severity: normal
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org
          Reporter: arjun.is at lostca dot se
                CC: libc-locales at sourceware dot org

executing:
$ LC_TIME=en_IN.UTF-8 date +%x

prints:
Tuesday 23 September 2014

This isn't the format used in India.

I have typically seen DD-MM-YY(YY) or DD/MM/YY(YY) in use in most places
including official tax forms, etc.

Here is the link to a copy of the Constitution of India:
http://india.gov.in/my-government/constitution-india/constitution-india-full-text

It appears to consistently use "DD-MM-YYYY" (when I looked at the main "Parts I
to XXII" document).

Additional references:

The online Visa application form [1] uses MM/DD/YYYY. The Wikipedia article [2]
mentions prevalence of MM/DD/YY in informal usage and MM-DD-YYYY in most
government documents and application forms. It offers a few citations.

Correction! This sentence was supposed to read:
> The online Visa application form [1] uses DD/MM/YYYY. The Wikipedia article
> [2] mentions prevalence of DD/MM/YY in informal usage and DD-MM-YYYY in most

I somehow switched MM and DD in my tired little mind.

The Gazette of India [1] (an official weekly containing notifications from
governmental agencies) uses DD/MM/YYYY and DD.MM.YYYY in most of its weekly
issues. It is, however, inconsistent.

Can you give reference from Unicode CLDR? Indian government is already member
of Unicode, we should use that as a reference.

So according to CLDR,

The full date format [1] for en_IN is: EEEE d MMMM y
The medium date format [2] is: dd-MMM-y
The short date format [3] is: dd/MM/yy

The explanation of the format strings [4] leads me to:

Standard: Wednesday 3 September 2014
Medium: 03-Sep-2014
Short: 03/09/2014

Now one could argue that the format currently shown for en_IN by `date +%x' is
correct as per the "full" date format. However, if I set my LC_TIME to
"en_GB.utf8", the date displayed for the same test case is *not* the long form
for en_GB according to CLDR. Also, from my personal experience, dates are
usually written 'DD/MM/(YY)YY' or 'DD-MM-(YY)YY' in India.

I must add that the format string guideline [4] is not clear upon the
difference between 'y' and 'yy', but it appears to me from the examples that
'y' represents the full year '2014' and 'yy' represents the year with the
century truncated '14'.

Hope this helps clear things up.
