 /**
  * Rounds the date according to the specified precision
  *
  * The precision parameter must be one of the following constants:
  *
  *  <code>DATE_PRECISION_YEAR</code>
  *  <code>DATE_PRECISION_MONTH</code>
  *  <code>DATE_PRECISION_DAY</code>
  *  <code>DATE_PRECISION_HOUR</code>
  *  <code>DATE_PRECISION_10MINUTES</code>
  *  <code>DATE_PRECISION_MINUTE</code>
  *  <code>DATE_PRECISION_10SECONDS</code>
  *  <code>DATE_PRECISION_SECOND</code>
  *
  * The precision can also be specified as an integral offset from
  * one of these constants, where the offset reflects a precision
  * of 10 to the power of the offset greater than the constant.
  * For example:
  *
  *  <code>DATE_PRECISION_YEAR - 1</code> rounds the date to the nearest 10
  *                                      years
  *  <code>DATE_PRECISION_YEAR - 3</code> rounds the date to the nearest 1000
  *                                      years
  *  <code>DATE_PRECISION_SECOND + 1</code> rounds the date to 1 decimal
  *                                        point of a second
  *  <code>DATE_PRECISION_SECOND + 1</code> rounds the date to 3 decimal
  *                                        points of a second
  *  <code>DATE_PRECISION_SECOND + 1</code> rounds the date to the nearest 10
  *                                        seconds (thus it is equivalent to
  *                                        DATE_PRECISION_10SECONDS)
  *
  * N.B. This function requires a time in UTC if both the precision is at
  * least DATE_PRECISION_SECOND and leap seconds are being counted, otherwise
  * any local time is acceptable.
  *
  * @param int   $pn_precision a 'DATE_PRECISION_*' constant
  * @param int   $pn_day       the day of the month
  * @param int   $pn_month     the month
  * @param int   $pn_year      the year
  * @param int   $pn_hour      the hour
  * @param int   $pn_minute    the minute
  * @param mixed $pn_second    the second as integer or float
  * @param bool  $pb_countleap whether to count leap seconds (defaults to
  *                             DATE_COUNT_LEAP_SECONDS)
  *
  * @return   array      array of year, month, day, hour, minute, second
  * @access   public
  * @static
  * @since    Method available since Release 1.5.0
