I want to store the current date generated from PHP into MongoDB collection as an ISO date formate.

```
ISODate("2012-11-02T08:40:12.569Z")

```

However I am not able to generate such Kind of **date** in php which will be stored in MongoDB as an **ISODate** format.

This is what I ve done.

```
 $d = new MongoDate(time());
 echo $d;

```

and it is outputting something like,

```
0.00000000 1353305590

```

which is not the format I need. How to do this?
