javascript Date().getTime() is not a function

Question

I'm trying to compare some Dates in javascript. For some reason, I'm getting "Tue May 01 2012 16:43:03 GMT+0900 (JST) has no method 'getTime'" Of course, strings don't have methods I started with this code inside a callback, but it was failing at `getTime()` on the line that creates `var age`: ``` for (var i = 0; i < array_of_usage_indices.length; i++) { store.get(array_of_usage_indices[i]['key'],function(may_need_gc) { if(may_need_gc) { var now = Date(); var created = Date(may_need_gc['value']); var age = now.getTime()-created.getTime(); } }) } ``` I've pared it down so my example page is literally just this: ``` date test

Accepted Answer

Try using `new` keyword to instantiate a new object so instead of this

```
var now = Date();
```

try this

```
var now = new Date();
```
