Comment:

 Ya, I think I'm understanding what you're meaning. Took me a good hour of
 playing around to make sense of it, too.

 My understanding of the code in that area and of your suggested change to
 the mysql2date call in touch_time() is that, it may prevent other locale
 (that use the standard calendar) from working properly. Trying to rephrase
 what you're suggesting:

  - You'd like to be able to output numbers in a non-latin format -- patch
 7753.2.diff lets you do just that, but I'll open a separate ticket else
 it'll get lost in this one.
  - You'd like the WP front end, and the back-end, to display dates in your
 localized calendar.

 By the latter point, you're not merely meaning changing the number format.
 You're also meaning that it should be able work with other calendars such
 as jalali, jewish, maya, julian, french revolutionary, and so on... These
 calendars don't all 7 days a week, or 365 days per year (some are lunar
 based).

 Making that happen would involve huge workflow changes in the WP code
 base: your suggested change to touch_time() would also be relevant to
 scores of other template tags, and the number_i18n filter is missing on
 the likes of pagination template tags. And I dare not even imagine how
 this translates into DB queries. How does one group posts by month in a
 non-gregorian calendar? :D

 The get_calendar() function outputs a Gregorian calendar in that format.
 It lets one change the start date, and that's about it... To make the
 existing code work with a non-gregorian calendar, we'd want to look into:

  - the number of days per week which isn't always 7 (assuming there is any
 kind of week concept to start with)
  - something to make special days work (in some calendars, some days don't
 belong in any month)
  - lunar months, and scores of other oddities, rather than gregorian
 months
  - non-decimal number support (some cultures count in base-5 and base-20)

 Personally, I'd advise to write a plugin...
