Job does nor run as expected

[rols2015]

I set a rule to run my job every 10 mins, but seems it's not running as expected. I would say it runs randomly each 20 or 30 sometimes 40 mins. Can someone advice what is wrong? Is it a bug?

//Sheduler
var cron = require('node-schedule');
var rule = new cron.RecurrenceRule();
rule.minute = 10;
cron.scheduleJob(rule, function(){
console.log(new Date(), 'Profile Update Job run!');

});

But when I use

cron.scheduleJob('0 /10 * * * *', function(){

  console.log(new Date(), 'Profile Update Job run!');

});```

it works fine

With recurrence rules you should use: js rule.minute: [ 0, 10, 20, 30, 40, 50 ]
