Can't see anything obviously wrong in either your or my code. However i see that mongoose has released a major version since i wrote this plugin; could be something related to that (though I can't find anything relevant in their still shitty docs).

I'm currently on vacation so I'll be able to look into it more in two weeks. Meanwhile: what version of node and mongoose are you using? Any other plugins?

Thanks Andreas.

Node: v0.12.7 NPM: 2.12.0 Mongoose: ~4.0.1 Monguurl: ~0.1.0

Regarding plugins, only using yours & timestamps:

var timestamps = require('mongoose-timestamp');
BookSchema.plugin(timestamps,  {
    createdAt: 'createdDate',
    updatedAt: 'modifiedDate'
});
