Symfony comes with some great i18n and l10n support. The DateHelper comes with functionality for templates to provide locale-specific date formats. There are a bunch of default formats that can be easily used as
format_date(strtotime('now'), 'P', 'en_US'); // Outputs 'Monday 7 June 2010'
format_date(strtotime('now'), 'P', 'fr_FR'); // Outputs 'Lundi 7 Juin 2010'
Some of the pre-defined patterns are constructed using special token patterns. These tokens can be passed to the 2nd parameter of the format_date() function above to generate custom formatted locale-specific date/time stamps.
format_date(strtotime('now'), 'EEE, MMMM dd, yyyy hh:mm a'); // Outputs 'Mon, June 07, 2010 12:40AM'
It doesn’t appear detailed information is available in any of the main documentation books or in the source code regarding the tokens available for date/time formatting, but I did come across a wiki page in the symfony trac.
