postman: How to add minutes to a dateTime while looping with JS?-CodePudding

I am trying to add 15 mins to a dateTime(2100-01-04T08:00:00) while looping. For each run I want to add 15 minutes , so it would be 2100-01-04T08:15:00 , 2100-01-04T08:30:00 and so on… I know I can do the below: var moment = require('moment'); moment().add(15, 'minutes').toISOString(); But this will add 15 minutes to the current moment time but I want to add 15 minutes to 2100-01-04T08:00:00.

Is this possible in postman?

CodePudding user response：

You can achieve this without using any third party libraries like momentJs. The default javascript Date object has methods for getting the minutes property for a date object - getMinutes() and also another method for updating this minutes property - setMinutes(). Combining them both, you can achieve your required answer.

let x = new Date('2100-01-04T08:00:00') 
for(let i = 0 ; i < 5; i   ){
  x.setMinutes(x.getMinutes() 15);
  console.log(x)
}

P.S, remove 'postman' from your question. It has nothing to do with the problem you are facing.

You can easily create an addMinutes() function to add a number of minutes to a date, you can then use a while loop to loop until a specified end date is reached.

In the example below, we'll add 15 minutes to the date until the end date is reached.

function addMinutes(date, minutes) {
    let newDate = new Date(date);
    newDate.setMinutes(newDate.getMinutes()   minutes);
    return newDate;
}

let date = new Date('2100-01-04T08:00:00');
let endDate = new  Date('2100-01-04T09:00:00');

let deltaMinutes = 15;
while (date <= endDate) {
    console.log(date.toLocaleString('en-US'));
    date = addMinutes(date, 15);
}
