MongoDB Date range query for past hour

[Question]

'm trying to write MongoDB query which will be return data from one hour ago. There is a column time with timestamps ("time" : NumberLong("1471953787012")) and this is how it looks in SQL:

select name from table
where time between (NOW() - INTERVAL 1 HOUR) AND (NOW())

How do I write a MongoDB query to find a date range from one hour ago? I'm trying with new Date() function but it doesn't work. Does anyone know what I'm doing wrong?

db.coll.find({ 
  "time" : { 
    $lt: new Date(), 
    $gte: new Date(new Date().setDate(new Date().getDate()-1))
  }   
})

db.entity.find({ $and:[
    {
    "timestamp": {
        $gte: new Date(ISODate().getTime() - 1000 * 60 * 60)
    }}, 
    { 
    "timestamp": {
        $lte: ISODate()
    }}
]})

Hope this helps...
