javascript date momentjs JavaScript

I tried several approaches but none seem to work. I'm working on a project and hit a roadblock. I'm trying to parse a series of timestamps that include timezone offsets in a standard format like `2023-10-05T14:30:00-07:00`. My goal is to convert these strings into JavaScript Date objects. However, I'm running into issues where some timestamps return `Invalid Date`. I've tried using the native `Date` constructor and the `Date.parse()` method, but I'm still having trouble with certain formats. Here’s a snippet of the code I’m using: ```javascript const timestamps = [ '2023-10-05T14:30:00-07:00', '2023-10-05T14:30:00Z', '2023-10-05T14:30:00+00:00', 'InvalidTimestamp' ]; timestamps.forEach(ts => { const date = new Date(ts); console.log(date); }); ``` When I run this code, I get `Invalid Date` for the last entry, which is expected. However, I’ve noticed that the `Date` object sometimes appears invalid for strings that I believe are correctly formatted. For example, it's returning `Invalid Date` for `2023-10-05T14:30:00-07:00` under certain conditions, even though it worked fine in other scripts. I also tried using the `moment.js` library which I thought would handle this better: ```javascript const moment = require('moment-timezone'); timestamps.forEach(ts => { const momentDate = moment(ts); console.log(momentDate.isValid() ? momentDate.format() : 'Invalid Date'); }); ``` This gives me `Invalid Date` for some of the timestamps as well. I suspect the issue might relate to how daylight saving time affects certain offsets, but I'm unsure how to handle this. What are the best practices for reliably parsing timestamps with timezone offsets in JavaScript? Is there a more robust library or method I should be using to avoid these issues? Any insights or suggestions would be greatly appreciated! Any ideas what could be causing this?
