I am setting a cron job to collect results from MongoDB database profiler. I'd like to collect results within a 24 hrs period. I plan to run mongo command with javascript.

Question is, in Mongo shell, how do I write a query to find a date range from 24 hrs ago? Such as:

db.system.profile.find({
    "timestamp" : {
        $lte : <current date & time>,
        $gt : <date & time 24 hrs ago>
    }
})


Found answer here:

db.system.profile.find({ 
  "timestamp" : { 
    $lt: new Date(), 
    $gte: new Date(new Date().setDate(new Date().getDate()-1))
  }   
})
