Mongoose DateTime Connundrum

 var Verify = require('../models/verify');
 
 var now = new Date();
 now.setDate = (now.getHours() - 1)
 
 
  Verify.find( //query today up to tonight
      {"created_on": {"$gte": now }})

Throws an error of type mismatch, I also tested and see the that the $lt and $gte takes on Date types.

function isMoreThanOneHourOld(datetime){
   var dateToCheck = moment(datetime);
   var now =  moment();
   return !dateToCheck.isAfter(now.subtract(1, 'hours'))
}

test with

isMoreThanOneHourOld(moment('2016-09-28 12:00:00')) //false

or

isMoreThanOneHourOld(moment('2016-09-28 10:00:00')) //true

Can you use it in the Mongoose Context like in my initial post, I know all this works but I need to check a dateTime field in a mongo collection
