尝试将其设为php值，而不是像这样的字符串：
var arrival_time = <?php echo $arrival_time; ?>;

Well, I don't know if this is a good practice but this is my method of passing a php value to javascript. 好吧，我不知道这是不是一个好习惯，但这是我将php值传递给javascript的方法。
<input type="hidden" value="<?php echo $arrivaltime; ?>" id="atime">
<script>
var arrival_time = $("#atime").val();
</script>
