// --------------------------------------------------------------------------------------------
// Job Schedule (uses node-cron)
// --------------------------------------------------------------------------------------------

// '* * * * * *' - runs every second
// '*/5 * * * * *' - runs every 5 seconds
// '10,20,30 * * * * *' - run at 10th, 20th and 30th second of every minute
// '0 * * * * *' - runs every minute
// '0 0 * * * *' - runs every hour (at 0 minutes and 0 seconds)
// But also more complex schedules e.g.

// '00 30 11 * * 1-5' - Runs every weekday (Monday through Friday) at 11:30:00 AM. It does not run on Saturday or Sunday.
// Sample code: running job every 10 minutes:

// var cron = require('cron');
// var cronJob = cron.job("0 */10 * * * *", function(){
//     // perform operation e.g. GET request http.get() etc.
//     console.info('cron job completed');
// });
// cronJob.start();
