- </span> * @class Ext.Date
- * A set of useful static methods to deal with date
- * Note that if Ext.Date is required and loaded, it will copy all methods / properties to
- * this object for convenience
- *
- * 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 class="">
- 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&#39;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
- MS 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');
- console.log(Ext.Date.format(dt, 'Y-m-d')); // 2007-01-10
- console.log(Ext.Date.format(dt, 'F j, Y, g:i a')); // January 10, 2007, 3:05 pm
- console.log(Ext.Date.format(dt, '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 Ext.Date, but to use them you can simply copy this
- * block of code into any script that is included after Ext.Date 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>
- Ext.Date.patterns = {
- ISO8601Long:"Y-m-d H:i:s",
- ISO8601Short:"Y-m-d",
- ShortDate: "n/j/Y",
- LongDate: "l, F d, Y",
- FullDateTime: "l, F d, Y g:i:s A",
- MonthDay: "F d",
- ShortTime: "g:i A",

- SortableDateTime: "Y-m-d\\TH:i:s",
- UniversalSortableDateTime: "Y-m-d H:i:sO",
- YearMonth: "F, Y"
- };
- </code></pre>
- *
- * Example usage:
- * <pre><code>
- var dt = new Date();
- console.log(Ext.Date.format(dt, Ext.Date.patterns.ShortDate));
- </code></pre>
- * <p>Developer-written, custom formats may be used by supplying both a formatting and a parsing function
- * which perform to specialized requirements. The functions are stored in {@link #parseFunctions} and {@link #formatFunctions}.</p>
