implementing Timezone Handling in Angular DatePipe - Unexpected Local Time Conversion

angular date timezone TypeScript

I'm writing unit tests and I'm getting frustrated with Hey everyone, I'm running into an issue that's driving me crazy... I'm working with issues with the Angular DatePipe when trying to display dates in the user's local timezone. I have a service that fetches a date string from the server in ISO 8601 format, for example, `2023-10-10T12:00:00Z`. I intend to convert this to the user's local timezone when displaying it in my component. I'm using Angular 14 and the following code in my template: ```html <p>{{ dateString | date: 'medium' }}</p> ``` However, it seems that the time displayed is incorrectly adjusted to another timezone instead of the user's local timezone. For instance, if a user in EST views this date, it should show `8:00 AM` instead of `12:00 PM` UTC. I tried specifying the timezone in the DatePipe like this: ```html <p>{{ dateString | date: 'medium':'UTC' }}</p> ``` But it didn't yield the expected results either. The output was still showing `12:00 PM` instead of the converted local time. I also experimented with different formats, but they all seem to default to UTC. Is there an scenario with how I'm handling the date string or how the DatePipe interprets it? I've checked that the date string from the server is correctly formatted and that the user's timezone is accurately detected. Any insights on how to resolve this or alternative approaches would be greatly appreciated! What am I doing wrong? I'm working on a web app that needs to handle this. How would you solve this? This is for a CLI tool running on macOS. Has anyone dealt with something similar? I'm using Typescript stable in this project. Is there a better approach?
