Incorrect Date Parsing in Node.js with Moment.js and Timezone Handling

node.js moment.js date-time javascript

I've spent hours debugging this and I'm working on a personal project and I'm working with an scenario with date parsing in a Node.js application using Moment.js (version 2.29.1). When I try to parse a date string with a timezone offset, the result seems to differ from what I expect. For instance, when I input the date string `2023-10-15T12:00:00-05:00`, I expect it to output the equivalent UTC time, but instead, it seems to retain the local timezone context instead. Here’s the code snippet I’m using: ```javascript const moment = require('moment-timezone'); const dateString = '2023-10-15T12:00:00-05:00'; const parsedDate = moment(dateString); console.log('Parsed Date in UTC:', parsedDate.utc().format()); ``` When I run this, I get an output of `2023-10-15T17:00:00Z`, which is correct, but if I check `parsedDate.format()`, I see it outputs `2023-10-15T12:00:00-05:00` instead of the expected UTC. I need it to store the UTC conversion in the database as well, but I want to keep track of the original timezone offset for later use. Is there a way to achieve this without losing the timezone information? I've tried using `parsedDate.toISOString()` but that doesn't seem to solve the scenario since it does not retain the original offset for later reference. Do I need to adjust my approach, or is there a specific method in Moment.js to handle this properly? Any guidance would be appreciated! My development environment is Linux. This is for a web app running on Linux. Am I approaching this the right way?
