/**
 * @class Date
 *
 * Creates `Date` instances which let you work with dates and times.
 *
 * If you supply no arguments, the constructor creates a `Date` object for today's
 * date and time according to local time. If you supply some arguments but not
 * others, the missing arguments are set to 0. If you supply any arguments, you
 * must supply at least the year, month, and day. You can omit the hours, minutes,
 * seconds, and milliseconds.
 *
 * The date is measured in milliseconds since midnight 01 January, 1970 UTC. A day
 * holds 86,400,000 milliseconds. The `Date` object range is -100,000,000 days to
 * 100,000,000 days relative to 01 January, 1970 UTC.
 *
 * The `Date` object provides uniform behavior across platforms.
 *
 * The `Date` object supports a number of UTC (universal) methods, as well as
 * local time methods. UTC, also known as Greenwich Mean Time (GMT), refers to the
 * time as set by the World Time Standard. The local time is the time known to the
 * computer where JavaScript is executed.
 *
 * Invoking `Date` in a non-constructor context (i.e., without the `new` operator)
 * will return a string representing the current time.
 *
 * Note that `Date` objects can only be instantiated by calling `Date` or using it
 * as a constructor; unlike other JavaScript object types, `Date` objects have no
 * literal syntax.
 *
 * # Several ways to assign dates
 *
 * The following example shows several ways to assign dates:
 *
 *     today = new Date();
 *     birthday = new Date("December 19, 1989 03:24:00");
 *     birthday = new Date(1989,11,19);
 *     birthday = new Date(1989,11,17,3,24,0);
 *
 * # Calculating elapsed time
 *
 * The following examples show how to determine the elapsed time between two dates:
 *
 *     // using static methods
 *     var start = Date.now();
 *     // the event you'd like to time goes here:
 *     doSomethingForALongTime();
 *     var end = Date.now();
 *     var elapsed = end - start; // time in milliseconds
 *
 *     // if you have Date objects
 *     var start = new Date();
 *     // the event you'd like to time goes here:
 *     doSomethingForALongTime();
 *     var end = new Date();
 *     var elapsed = end.getTime() - start.getTime(); // time in milliseconds
 *
 *     // if you want to test a function and get back its return
 *     function printElapsedTime (fTest) {
 *         var nStartTime = Date.now(), vReturn = fTest(), nEndTime = Date.now();
 *         alert("Elapsed time: " + String(nEndTime - nStartTime) + "
 *         milliseconds");
 *         return vReturn;
 *     }
 *
 *     yourFunctionReturn = printElapsedTime(yourFunction);
 *
 * # ISO 8601 formatted dates
 *
 * The following example shows how to formate a date in an ISO 8601 format using
 * UTC:
 *
 *     // use a function for the exact format desired...
 *     function ISODateString(d){
 *     function pad(n){return n<10 ? '0'+n : n}
 *     return d.getUTCFullYear()+'-'
 *         + pad(d.getUTCMonth()+1)+'-'
 *         + pad(d.getUTCDate())+'T'
 *         + pad(d.getUTCHours())+':'
 *         + pad(d.getUTCMinutes())+':'
 *         + pad(d.getUTCSeconds())+'Z'}
 *
 *     var d = new Date();
 *     print(ISODateString(d)); // prints something like 2009-09-28T19:03:12Z

/**

//Methods

/**
 * @method now
 * @static
 * Returns the numeric value corresponding to the current time.
 *
 * The `now` method returns the milliseconds elapsed since 1 January 1970 00:00:00 UTC up until now as
 * a number.
 *
 * When using `now` to create timestamps or unique IDs, keep in mind that the resolution may be 15
 * milliseconds on Windows, so you could end up with several equal values if `now` is called multiple
 * times within a short time span.
 *
 * @return {Number} Returns the number of milliseconds elapsed since 1 January 1970 00:00:00 UTC.
 */

/**
 * @method parse
 * @static
 * Parses a string representation of a date, and returns the number of milliseconds
 * since January 1, 1970, 00:00:00, local time.
 *
 * The `parse` method takes a date string (such as `"Dec 25, 1995"`) and returns the number of
 * milliseconds since January 1, 1970, 00:00:00 UTC. The local time zone is used to interpret
 * arguments that do not contain time zone information. This function is useful for setting date
 * values based on string values, for example in conjunction with the `setTime` method and the
 * {@link Date} object.
 *
 * Given a string representing a time, parse returns the time value. It accepts the IETF standard (RFC
 * 1123 Section 5.2.14 and elsewhere) date syntax: `"Mon, 25 Dec 1995 13:30:00 GMT"`. It understands
 * the continental US time-zone abbreviations, but for general use, use a time-zone offset, for
 * example, `"Mon, 25 Dec 1995 13:30:00 GMT+0430"` (4 hours, 30 minutes east of the Greenwich
 * meridian). If you do not specify a time zone, the local time zone is assumed. GMT and UTC are
 * considered equivalent.
 *
 * ### Using parse
 *
 * If `IPOdate` is an existing `Date` object, then you can set it to August 9, 1995 (local time) as
 * follows:
 *
 *     IPOdate.setTime(Date.parse("Aug 9, 1995"));
 *
 * Some other examples:
 *
 *     // Returns 807937200000 in time zone GMT-0300, and other values in other
 *     // timezones, since the argument does not specify a time zone.
 *     Date.parse("Aug 9, 1995");
 *
 *     // Returns 807926400000 no matter the local time zone.
 *     Date.parse("Wed, 09 Aug 1995 00:00:00 GMT");
 *
 *     // Returns 807937200000 in timezone GMT-0300, and other values in other
 *     // timezones, since there is no time zone specifier in the argument.
 *     Date.parse("Wed, 09 Aug 1995 00:00:00");
 *
 *     // Returns 0 no matter the local time zone.
 *     Date.parse("Thu, 01 Jan 1970 00:00:00 GMT");
 *
 *     // Returns 14400000 in timezone GMT-0400, and other values in other
 *     // timezones, since there is no time zone specifier in the argument.
 *     Date.parse("Thu, 01 Jan 1970 00:00:00");
 *
 *     // Returns 14400000 no matter the local time zone.
 *     Date.parse("Thu, 01 Jan 1970 00:00:00 GMT-0400");
 *
 * @param {String} dateString A string representing a date.
 * @return {Number} Number of milliseconds since January 1, 1970, 00:00:00, local time.
 */

/**
 * @method UTC
 * @static
 * Accepts the same parameters as the longest form of the constructor, and returns
 * the number of milliseconds in a `Date` object since January 1, 1970, 00:00:00,
 * universal time.
 *
 * `UTC` takes comma-delimited date parameters and returns the number of milliseconds between January
 * 1, 1970, 00:00:00, universal time and the time you specified.
 *
 * You should specify a full year for the year; for example, 1998. If a year between 0 and 99 is
 * specified, the method converts the year to a year in the 20th century (1900 + year); for example,
 * if you specify 95, the year 1995 is used.
 *
 * The `UTC` method differs from the `Date` constructor in two ways.
 * *   `Date.UTC` uses universal time instead of the local time.
 * *   `Date.UTC` returns a time value as a number instead of creating a `Date` object.
 *
 * If a parameter you specify is outside of the expected range, the `UTC` method updates the other
 * parameters to allow for your number. For example, if you use 15 for month, the year will be
 * incremented by 1 (year + 1), and 3 will be used for the month.
 *
 * Because `UTC` is a static method of `Date`, you always use it as `Date.UTC()`, rather than as a
 * method of a `Date` object you created.
*
 * The following statement creates a `Date` object using GMT instead of local time:
 *
 *     gmtDate = new Date(Date.UTC(96, 11, 1, 0, 0, 0));
 *
 * @param {Number} year A year after 1900.
 * @param {Number} month An integer between 0 and 11 representing the month.
 * @param {Number} date An integer between 1 and 31 representing the day of the month.
 * @param {Number} hrs An integer between 0 and 23 representing the hours.
 * @param {Number} min An integer between 0 and 59 representing the minutes.
 * @param {Number} sec An integer between 0 and 59 representing the seconds.
 * @param {Number} ms An integer between 0 and 999 representing the milliseconds.
 * @return {Date} Number of milliseconds since January 1, 1970, 00:00:00, universal time.

/**
