2 </span> * @class Ext.Date
3 * A set of useful static methods to deal with date
4 * Note that if Ext.Date is required and loaded, it will copy all methods / properties to
5 * this object for convenience
7 * The date parsing and formatting syntax contains a subset of
8 * <a href="http://www.php.net/date">PHP's date() function</a>, and the formats that are
9 * supported will provide results equivalent to their PHP versions.
11 * The following is a list of all currently supported formats:
12 * <pre class="">
13 Format Description Example returned values
14 ------ ----------------------------------------------------------------------- -----------------------
15 d Day of the month, 2 digits with leading zeros 01 to 31
16 D A short textual representation of the day of the week Mon to Sun
17 j Day of the month without leading zeros 1 to 31
18 l A full textual representation of the day of the week Sunday to Saturday
19 N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
20 S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
21 w Numeric representation of the day of the week 0 (for Sunday) to 6 (for Saturday)
22 z The day of the year (starting from 0) 0 to 364 (365 in leap years)
23 W ISO-8601 week number of year, weeks starting on Monday 01 to 53
24 F A full textual representation of a month, such as January or March January to December
25 m Numeric representation of a month, with leading zeros 01 to 12
26 M A short textual representation of a month Jan to Dec
27 n Numeric representation of a month, without leading zeros 1 to 12
28 t Number of days in the given month 28 to 31
29 L Whether it&#39;s a leap year 1 if it is a leap year, 0 otherwise.
30 o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
31 belongs to the previous or next year, that year is used instead)
32 Y A full numeric representation of a year, 4 digits Examples: 1999 or 2003
33 y A two digit representation of a year Examples: 99 or 03
34 a Lowercase Ante meridiem and Post meridiem am or pm
35 A Uppercase Ante meridiem and Post meridiem AM or PM
36 g 12-hour format of an hour without leading zeros 1 to 12
37 G 24-hour format of an hour without leading zeros 0 to 23
38 h 12-hour format of an hour with leading zeros 01 to 12
39 H 24-hour format of an hour with leading zeros 00 to 23
40 i Minutes, with leading zeros 00 to 59
41 s Seconds, with leading zeros 00 to 59
42 u Decimal fraction of a second Examples:
43 (minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
46 999876543210 (i.e. 0.999876543210s)
47 O Difference to Greenwich time (GMT) in hours and minutes Example: +1030
48 P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
49 T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
50 Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
53 1) If unspecified, the month / day defaults to the current month / day, 1991 or
54 the time defaults to midnight, while the timezone defaults to the 1992-10 or
55 browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
56 and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
57 are optional. 1995-07-18T17:21:28-02:00 or
58 2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
59 least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
60 of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
61 Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or
62 date-time granularity which are supported, or see 2000-02-13T21:25:33
63 http://www.w3.org/TR/NOTE-datetime for more info. 2001-01-12 22:26:34
64 U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
65 MS Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
66 \/Date(1238606590509+0800)\/
69 * Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
70 * <pre><code>
72 // 'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'
74 var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
75 console.log(Ext.Date.format(dt, 'Y-m-d')); // 2007-01-10
76 console.log(Ext.Date.format(dt, 'F j, Y, g:i a')); // January 10, 2007, 3:05 pm
77 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
78 </code></pre>
80 * Here are some standard date/time patterns that you might find helpful. They
81 * are not part of the source of Ext.Date, but to use them you can simply copy this
82 * block of code into any script that is included after Ext.Date and they will also become
83 * globally available on the Date object. Feel free to add or remove patterns as needed in your code.
84 * <pre><code>
86 ISO8601Long:"Y-m-d H:i:s",
87 ISO8601Short:"Y-m-d",
88 ShortDate: "n/j/Y",
89 LongDate: "l, F d, Y",
90 FullDateTime: "l, F d, Y g:i:s A",
91 MonthDay: "F d",
92 ShortTime: "g:i A",
93 LongTime: "g:i:s A",
94 SortableDateTime: "Y-m-d\\TH:i:s",
95 UniversalSortableDateTime: "Y-m-d H:i:sO",

103 console.log(Ext.Date.format(dt, Ext.Date.patterns.ShortDate));

105 * <p>Developer-written, custom formats may be used by supplying both a formatting and a parsing function
106 * which perform to specialized requirements. The functions are stored in {@link #parseFunctions} and {@link #formatFunctions}.</p>
111 * Most of the date-formatting functions below are the excellent work of Baron Schwartz.
112 * (see http://www.xaprb.com/blog/2005/12/12/javascript-closures-for-runtime-efficiency/)
113 * They generate precompiled functions from format patterns instead of parsing and
114 * processing each pattern every time a date is formatted. These functions are available
115 * on every Date object.
