Class

TimelineDate

Converts date strings to TimelineJS3-compatible date arrays.

Code

public function __construct($date_string, DateTimeZone $timezone = NULL) {
  $this->date_string = $date_string;

  // Disallow empty date strings.  They will cause DateTime::__construct() to
  // return a date object with the current time.
  if (empty($date_string)) {
    throw new Exception('Empty date strings are not allowed.');
  }

  // Check for date strings that only include a year value.
  if (is_numeric($date_string)) {

    // Append '-01-01' to year-only values.  By specifying a month and day
    // before the value is parsed, year-only values can be used as input.
    $date_string .= '-01-01';
  }

  // Explicitly set timezone for versions of PHP prior to 5.3.6.
  // @see https://bugs.php.net/bug.php?id=52063
  if (phpversion() < '5.3.6' && $timezone === NULL) {
    $timezone = new DateTimeZone(date_default_timezone_get());
  }
  parent::__construct($date_string, $timezone);
