 * The Date class is a fork of Joomla's Date. We had to fork that code in April 2017 when Joomla! 7.0 was released with
 * an untested change that completely broke date handling on PHP 7.0 and earlier versions. Since we can no longer trust
 * Joomla's core date and time handling we are providing our own, stable code.
 *
 * Date is a class that stores a date and provides logic to manipulate and render that date in a variety of formats.
 *
 * @method  Date|bool  add(DateInterval $interval)  Adds an amount of days, months, years, hours, minutes and seconds
 *          to a Date object.
 * @method  Date|bool  sub(DateInterval $interval)  Subtracts an amount of days, months, years, hours, minutes and
 *          seconds from a Date object.
 * @method  Date|bool  modify($modify)              Alter the timestamp of this object by incre-/decrementing in a
 *          format accepted by strtotime().
 *
 * @property-read  string  $daysinmonth   t - Number of days in the given month.
 * @property-read  string  $dayofweek     N - ISO-8601 numeric representation of the day of the week.
 * @property-read  string  $dayofyear     z - The day of the year (starting from 0).
 * @property-read  boolean $isleapyear    L - Whether it's a leap year.
 * @property-read  string  $day           d - Day of the month, 2 digits with leading zeros.
 * @property-read  string  $hour          H - 24-hour format of an hour with leading zeros.
 * @property-read  string  $minute        i - Minutes with leading zeros.
 * @property-read  string  $second        s - Seconds with leading zeros.
 * @property-read  string  $microsecond   u - Microseconds with leading zeros.
 * @property-read  string  $month         m - Numeric representation of a month, with leading zeros.
 * @property-read  string  $ordinal       S - English ordinal suffix for the day of the month, 2 characters.
 * @property-read  string  $week          W - ISO-8601 week number of year, weeks starting on Monday.
 * @property-read  string  $year          Y - A full numeric representation of a year, 4 digits.
