/**
 * Defines how DateTime values are formatted and displayed, depending 
 * on the culture.
 * 
 * This class contains information, such as date patterns, time patterns, 
 * and AM/PM designators. 
 *
 * To create a sfDateTimeFormatInfo for a specific culture, create a 
 * sfCultureInfo for that culture and retrieve the sfCultureInfo.sfDateTimeFormat 
 * property. For example:
 * <code>
 * $culture = new sfCultureInfo('en_AU');
 * $dtfi = $culture->DateTimeFormat;
 * </code>
 * 
 * To create a sfDateTimeFormatInfo for the invariant culture, use 
 * <code>
 * sfDateTimeFormatInfo::getInstance($culture=null);
 * </code>
 * you may pass a sfCultureInfo parameter $culture to get the sfDateTimeFormatInfo
 * for a specific culture.
 *
 * sfDateTime values are formatted using standard or custom patterns stored in 
 * the properties of a sfDateTimeFormatInfo.
 * 
 * The standard patterns can be replaced with custom patterns by setting the 
 * associated properties of sfDateTimeFormatInfo.
 *
 * The following table lists the standard format characters for each standard 
 * pattern and the associated sfDateTimeFormatInfo property that can be set to 
 * modify the standard pattern. The format characters are case-sensitive;
 * for example, 'g' and 'G' represent slightly different patterns.
 *
 * <code>
 *  Format Character    Associated Property     Example Format Pattern (en-US)
 *  --------------------------------------------------------------------------
 *  d                   ShortDatePattern        MM/dd/yyyy 
 *  D                   LongDatePattern         dddd, dd MMMM yyyy 
 *  F                   FullDateTimePattern     dddd, dd MMMM yyyy HH:mm:ss
 *  m, M                MonthDayPattern         MMMM dd 
 *  r, R                RFC1123Pattern          ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
 *  s                   SortableDateTimePattern yyyy'-'MM'-'dd'T'HH':'mm':'ss 
 *  t                   ShortTimePattern        HH:mm 
 *  T                   LongTimePattern         HH:mm:ss 
 *  Y                   YearMonthPattern        yyyy MMMM
