I have a simple piece of PHP ode at the moment:

```
echo strtotime("2011-06-26T10:00:36+10:00");

```

Which is returning:

```
1309046436

```

If I run the equivalent via JavaScript:

```
new Date("2011-06-26T10:00:36+10:00").valueOf();

```

I get the following:

```
1309046436000

```

As you can see the PHP version is returning 3 digits too short. Do you know what the problem is? Is it a memory issue?
