title: Date comparison with Mongoose
body: <p>I'm trying to find a user with a user that has a location that is newer or older than a certain date.</p>
  
  <p><strong>Schema</strong></p>
  
  <pre><code>var userSchema = new Schema({
      firstName: String,
      lastName: String,
      email: String,
      facebookId: String,
      googleId: String,
      token: {type: String, unique: true, required: true},
      friends: [userSchema],
      location: {
          type: {
              timestamp: Date,
              accuracy: Number,
              coordinates: {
                  lat: Number,
                  lng: Number
              }
          },
          default: null
      }
  }, {
  </code></pre>
  
  <p><strong>Query</strong></p>
  
  <pre><code>userSchema.statics.findRecentUpdates = function (ids, minutesSinceLast, callback) {
      var recentDate = new Date().removeMinutes(minutesSinceLast);
      this.find(
          {'location.timestamp': {$lt: recentDate}},
          callback
      );
  }
  </code></pre>
  
  <p><strong>Data</strong></p>
  
  <pre><code>db.users.find();
  { "__v" : 1, "_id" : ObjectId("53cecb60fe7d090000030328"), "email" : "JzLrmXy@givnZhE.com", "facebookId" : "9138129367", "firstName" : "Cornel", "friends" : [  ObjectId("53cecb4dfe7d090000030327") ], "lastName" : "GD", "location" : { "coordinates" : { "lat" : 18.040808, "lng" : 59.330557 }, "timestamp" : 1406061408964, "accuracy" : 1 }, "token" : "988bb52b-cc0c-492d-8c75-f1f7d882157d" }
  { "__v" : 20, "_id" : ObjectId("53cf668eff9ef40000f76ce5"), "email" : "CZteADE@WFdFFiQ.com", "facebookId" : "5762365752", "firstName" : "Yuan", "friends" : [ ], "lastName" : "vh", "location" : { "accuracy" : 3, "coordinates" : { "lat" : 59.356862, "lng" : 17.996661 }, "timestamp" : 1406101134199 }, "token" : "51278cb7-9e55-4cc5-b635-7cd289b2fa6a" }
  { "__v" : 21, "_id" : ObjectId("53cecb4dfe7d090000030327"), "email" : "s@gmail.com", "facebookId" : "7237853051", "firstName" : "M", "friends" : [  ObjectId("53cecb60fe7d090000030328") ], "lastName" : "H", "location" : { "accuracy" : 0, "coordinates" : { "lng" : 18.0246476, "lat" : 59.3827026 }, "timestamp" : 1413838822856 }, "token" : "5d870480-05c0-4a83-ae44-cfe39692d308" }
  </code></pre>
  
  <p>No matter what I set the date to I always get an empty result. Trying with <code>'location.accuracy'</code> and setting less or greater than an that works.</p>
