+ * @class Date
+ *
+ * The date parsing and formatting syntax contains a subset of
+ * <a href="http://www.php.net/date">PHP's date() function</a>, and the formats that are
+ * supported will provide results equivalent to their PHP versions.
+ *
+ * The following is a list of all currently supported formats:
+ * <pre>
+Format Description Example returned values
+------ ----------------------------------------------------------------------- -----------------------
+ d Day of the month, 2 digits with leading zeros 01 to 31
+ D A short textual representation of the day of the week Mon to Sun
+ j Day of the month without leading zeros 1 to 31
+ l A full textual representation of the day of the week Sunday to Saturday
+ N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
+ S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
+ w Numeric representation of the day of the week 0 (for Sunday) to 6 (for Saturday)
+ z The day of the year (starting from 0) 0 to 364 (365 in leap years)
+ W ISO-8601 week number of year, weeks starting on Monday 01 to 53
+ F A full textual representation of a month, such as January or March January to December
+ m Numeric representation of a month, with leading zeros 01 to 12
+ M A short textual representation of a month Jan to Dec
+ n Numeric representation of a month, without leading zeros 1 to 12
+ t Number of days in the given month 28 to 31
+ L Whether it's a leap year 1 if it is a leap year, 0 otherwise.
+ o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
+ belongs to the previous or next year, that year is used instead)
+ Y A full numeric representation of a year, 4 digits Examples: 1999 or 2003
+ y A two digit representation of a year Examples: 99 or 03
+ a Lowercase Ante meridiem and Post meridiem am or pm
+ A Uppercase Ante meridiem and Post meridiem AM or PM
+ g 12-hour format of an hour without leading zeros 1 to 12
+ G 24-hour format of an hour without leading zeros 0 to 23
+ h 12-hour format of an hour with leading zeros 01 to 12
+ H 24-hour format of an hour with leading zeros 00 to 23
+ i Minutes, with leading zeros 00 to 59
+ s Seconds, with leading zeros 00 to 59
+ u Decimal fraction of a second Examples:
+ (minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
+ 100 (i.e. 0.100s) or
+ 999 (i.e. 0.999s) or
+ 999876543210 (i.e. 0.999876543210s)
+ O Difference to Greenwich time (GMT) in hours and minutes Example: +1030
+ P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
+ T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
+ Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
+ c ISO 8601 date
+ Notes: Examples:
+ 1) If unspecified, the month / day defaults to the current month / day, 1991 or
+ the time defaults to midnight, while the timezone defaults to the 1992-10 or
+ browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
+ and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
+ are optional. 1995-07-18T17:21:28-02:00 or
+ 2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
+ least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
+ of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
+ Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or
+ date-time granularity which are supported, or see 2000-02-13T21:25:33
+ http://www.w3.org/TR/NOTE-datetime for more info. 2001-01-12 22:26:34
+ U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
+ M$ Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
+ \/Date(1238606590509+0800)\/
+</pre>
+ *
+ * Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
+ * <pre><code>
+// Sample date:
+// 'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'
+
+var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
+document.write(dt.format('Y-m-d')); // 2007-01-10
+document.write(dt.format('F j, Y, g:i a')); // January 10, 2007, 3:05 pm
+document.write(dt.format('l, \\t\\he jS \\of F Y h:i:s A')); // Wednesday, the 10th of January 2007 03:05:01 PM
+</code></pre>
+ *
+ * Here are some standard date/time patterns that you might find helpful. They
+ * are not part of the source of Date.js, but to use them you can simply copy this
+ * block of code into any script that is included after Date.js and they will also become
+ * globally available on the Date object. Feel free to add or remove patterns as needed in your code.
+ * <pre><code>
+Date.patterns = {
