How to find time difference in seconds using moment.js?

@lottie 

To find the time difference in seconds between two moments using moment.js, you can use the moment.duration() method. First, you need to create moment objects for the two timestamps you want to compare. Then, you can use the duration() method to calculate the duration between the two moments. Finally, you can use the asSeconds() method to get the time difference in seconds.

Here's an example code snippet to demonstrate how to find the time difference in seconds using moment.js:

// Import moment.js library
const moment = require('moment');

// Create moment objects for the two timestamps
const start = moment('2022-01-01 12:00:00', 'YYYY-MM-DD HH:mm:ss');
const end = moment('2022-01-01 12:30:00', 'YYYY-MM-DD HH:mm:ss');

// Calculate the duration between the two moments
const duration = moment.duration(end.diff(start));

// Get the time difference in seconds
const timeDiffInSeconds = duration.asSeconds();

console.log(timeDiffInSeconds); // Output: 1800 seconds

In this example, we create moment objects for two timestamps '2022-01-01 12:00:00' and '2022-01-01 12:30:00' and calculate the duration between them. The time difference in seconds is then calculated and displayed in the console.
