/** * @class Ext.Date * This class defines some basic methods for handling dates. * * 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: * * 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 represented as the local time with an offset to UTC appended. * 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 * C An ISO date string as implemented by the native Date object's 1962-06-17T09:21:34.125Z * [Date.toISOString](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) * method. This outputs the numeric part with *UTC* hour and minute * values, and indicates this by appending the `'Z'` timezone * identifier. * 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 * * 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.
