node.js - Which SchemaType in Mongoose is Best for Timestamp?

Question

I'm using Mongoose, MongoDB, and Node.

I would like to define a schema where one of its fields is a dateimestamp.

I would like to use this field in order to return all of the records that have been updated in the last 5 minutes.

Due to the fact that in Mongoose I can't use the Timestamp() method I understand that my only option is to use the following Javascript method:

time : { type: Number, default: (new Date()).getTime() } 

It's probably not the most efficient way for querying a humongous DB. I would really appreciate it if someone could share a more efficient way of implementing this.

Is there any way to implement this with Mongoose and be able to use a MongoDB timestamp?

Mongoose now support timestamps for collections.

Please consider the answer of @bobbyz below. Maybe this is what you are looking for.

Original answer

Mongoose supports a Date type (which is basically a timestamp):

time : { type : Date, default: Date.now }

With the above field definition, any time you save a document with an unset time field, Mongoose will fill in this field with the current time.
