</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
|
* [PHP's `date()` function](http://www.php.net/date), 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

|
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

|
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)\/
|
time A javascript millisecond timestamp 1350024476440
|
timestamp A UNIX timestamp (same as U) 1350024866
|
</pre>
|
*
|
* Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
|
*
|
* // 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
|
*
|
* 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.
|
*
|
* 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",
|
* LongTime: "g:i:s A",
|
* SortableDateTime: "Y-m-d\\TH:i:s",
|
* UniversalSortableDateTime: "Y-m-d H:i:sO",
|
* YearMonth: "F, Y"
|
* };
|
*
|
* Example usage:
|
*
|
* var dt = new Date();
|
* console.log(Ext.Date.format(dt, Ext.Date.patterns.ShortDate));
|
*
|
* 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}.

</span> * Provides a convenient method for performing basic date arithmetic. This method

|
* a new Date instance containing the resulting date value.
|
*
|
* Examples:
|
*
|
* // Basic usage:
|
* var dt = Ext.Date.subtract(new Date('10/29/2006'), Ext.Date.DAY, 5);
|
* console.log(dt); // returns 'Tue Oct 24 2006 00:00:00'
|
*
|
* // Negative values will be added:
|
* var dt2 = Ext.Date.subtract(new Date('10/1/2006'), Ext.Date.DAY, -5);
|
* console.log(dt2); // returns 'Fri Oct 6 2006 00:00:00'
|
*
|
* // Decimal values can be used:
|
* var dt3 = Ext.Date.subtract(new Date('10/1/2006'), Ext.Date.DAY, 1.25);
|
* console.log(dt3); // returns 'Fri Sep 29 2006 06:00:00'
|
*
|
* @param {Date} date The date to modify
|
* @param {String} interval A valid date interval enum value.
|
* @param {Number} value The amount to subtract from the current date.
|
* @return {Date} The new Date instance.
