Hi there,
So I need execute a job each hour, each 15 minutes exactly, independent from the deploy hour.

It's the first time that I use this GEM and it's my first app in Ruby :)

In node.js my code to do this is

var job = new CronJob('0 */15 * * * *', function () {
        do something....
    }, null, true, "");

I try 2 different approach

1) every hours at : 00/15/30/45

Crono.perform(myJob).every 1.hours,          at: {min:00}
Crono.perform(myJob).every 1.hours,          at: {min:15}
Crono.perform(myJob).every 1.hours,          at: {min:30}
Crono.perform(myJob).every 1.hours,          at: {min:45}

NOT WORK! period should be at least 1 day to use 'at'

2) every days each hours at : 00/15/30/45

Crono.perform(myJob).every 1.day,          at: {hour: *, min:00}
Crono.perform(myJob).every 1.day,          at: {hour: *, min:15}
Crono.perform(myJob).every 1.day,          at: {hour: *, min:30}
Crono.perform(myJob).every 1.day,          at: {hour: *, min:45}

NOT WORK! syntax error, unexpected * (SyntaxError)

Any suggestion??

@marcosomma Thank you for the report. Now you can setup it as:

Crono.perform(myJob).every 1.hours,          at: {min:00}
Crono.perform(myJob).every 1.hours,          at: {min:15}
Crono.perform(myJob).every 1.hours,          at: {min:30}
Crono.perform(myJob).every 1.hours,          at: {min:45}
