node.js - Converting a mongo stored date back into milliseconds since Unix epoch when loaded? -

i using mongoose & node.js webserver.

as part of 1 of document schemas, have 'timestamp' field. line in schema is: timestamp: { type: date, default: date.now }

this works fine, , allows me retrieve documents based on timestamp, however, saves isodate format described here: http://docs.mongodb.org/manual/core/document/#date, this:

"timestamp":"2013-04-04t19:31:38.514z"

i don't mind this, send client is. means have use date.parse() @ client end before can comparative operations it.

is there way either store date integer, or automatically convert 1 when it's retrieved?

is there reason should keep how is, , deal @ client end?

thanks in advance.

you can add numerical milliseconds version of timestamp virtual attribute on schema:

schema.virtual('timestamp_ms').get(function() {   return this.timestamp.gettime(); });

then can enable virtual field's inclusion in toobject calls on model instances via option on schema:

var schema = new schema({   timestamp: date }, {   toobject: { getters: true } });
