Within MongoDB 3.6 you can now use $dateFromString (https://docs.mongodb.com/manual/reference/operator/aggregation/dateFromString/)

db.logmessages.aggregate( [ {
   $project: {
      date: {
         $dateFromString: {
            dateString: '$date'
         }
      }
   }
}, { $sort: { date : 1} } ] )
