  print_r($sCurrentTime);
  echo "<br />var_dump: ";
  var_dump($sCurrentTime);
  echo "<br />Converted To Float: ";
  list($sFraction, $sSecond) = explode(" ", $sCurrentTime);
  echo ((float)$sSecond + (float)$sFraction);
  echo "<br />Note: The float precision may cause rounding if the precision is too low.";
?>
