node.js中setTimeout的最大时间限制

Question

I have registered some setTimeout functions in node like below.

//Formula: minutes * 60 > seconds * 1000 > miliseconds.
setTimeout(() => {console.log("One minute")}, 1 * 60 * 1000)        //delay 60000
setTimeout(() => {console.log("Five minutes")}, 5 * 60 * 1000)      //delay 300000
setTimeout(() => {console.log("Ten minutes")}, 10 * 60 * 1000)      //delay 600000
setTimeout(() => {console.log("Thirty minutes")}, 30 * 60 * 1000)   //delay 1800000
setTimeout(() => {console.log("One hour")}, 60 * 60 * 1000)         //delay 3600000
setTimeout(() => {console.log("Two hours")}, 120 * 60 * 1000)       //delay 7200000
setTimeout(() => {console.log("Five hours")}, 300 * 60 * 1000)      //delay 18000000

Now the issue is setTimeout that take more than 10 minutes is not working when I read setTimeout documentation it's support 24.8 days .

When delay is larger than 2147483647 or less than 1, the delay will be set to 1

All delay's value is less than 2147483647 than why it is not working ???

Answer 1

Finally I got answer when I created issue on node.js repo, basically it's not node.js but heroku issue.
In heroku free dynos are unique because they go to sleep after 30 minutes of inactivity so more than 30 minutes of time is not working

Answer 2

I am not sure what you exactly want to achieve here. If you want to execute something at later stage use Cron instead of setTimeout .

And answer to your original question is

JavaScript store the delay as a 32-bit signed Integer internally. This causes an Integer overflow when using delays larger than 2147483647, resulting in the timeout being executed immediately.

Above code is working fine.
