Assuming you're trying to do this in the shell:

 tmp = db.drives.find({}, {_id:0, driveDate:1}).sort({driveDate:1}).limit(1).toArray()[0]

find returns a cursor that you need to iterate over to retrieve the actual documents. Calling toArray on the cursor converts it to an array of docs.

After some time figuring out, I got the solution. here it is, for future reference:

var myDate = cursor.next()

That's it. Thanks for your help
