Snippet: Time class for PHP

17 Oct 2008

Pretty boring snippet today, but I find it immensely useful. My time class provides representations of periods from OneMinute to OneYear. It only has one method which will calculate an absolute time by adding a given time period to the current time. You can optionally provide a format intended for use by the date function to return a formatted string rather than a timestamp.

Hope you find it useful too.

class Time
{
  const OneMinute = 60;
  const FiveMinutes = 300;
  const TenMinutes = 600;
  const FifteenMinutes = 900;
  const HalfHour = 1800;
  const OneHour = 3600;
  const SixHours = 21600;
  const HalfDay = 43200;
  const OneDay = 86400;
  const SevenDays = 604800;
  const ThirtyDays = 2592000;
  const OneYear = 31536000;

  public static function GetAbsolute($time, $format = false)
  {
    if (is_numeric($time) and $time < (time()-1)) {
      $time = time() + $time;
    } else {
      $time = strtotime($time);
    }
    return (false === $format ? $time : date($format, $time));
  }
}
