Better patch for Buddhist era in Drupal

Submitted by sugree on Sat, 12/22/2007 - 13:10

After the first patching attempt to display Buddhist era in Drupal correctly, I found an annoying issue as a result at Drupal Thailand while trying to edit my own comment. The node's date is formatted by format_date() using custom format with Y. Unfortunately, the date string is converted back to seconds using strtotime() which doesn't recognize Buddhist era, says 2550. I had to change 2550 to 2007 to save that comment.

After thinking for a while, I found better solution by adding 'X' and 'x' for localized year like Buddhist era and let users specify custom date formats in settings.php.

settings.php

setlocale(LC_TIME, 'th_TH.UTF8');
$conf = array(
  'date_format_short' => 'm/d/X - H:i',
  'date_format_large' => 'l, F j, X - H:i',
  'date_format_medium' => 'D, m/d/X - H:i',
);
