有没有办法检查日期是否少于1小时？

像这样的东西:

<script>
// old date
var olddate = new Date("February 9, 2012, 12:15");

// current date
var currentdate = new Date();

if (olddate >= currentdate - 1 hour) {
    alert("newer than 1 hour");
else {
    alert("older than 1 hour");
}
</script>

另外,不同的问题 - 是否有办法增加约会时间？

像这样:

<script>
var olddate = new Date("February 9, 2012, 12:15") + 15 HOURS; // output: February 10, 2012, 3:15
</script>
