How to disable Workshop time zone conversion from a Typescript Function

I wrote a typescript function that returns a timestamp based off of a string year, seen below:

When I test this in both the “Live Preview” and “Published” functions, it produces the results one would expect:


Why then does Workshop convert that timestamp into my local time (Workshop seems to be assuming the time zone of the timestamp is UTC) without any clear way to disable that behavior? Here are the results from the function in Workshop:


I can’t just assume what time zone the user/s are in and try to statically type the time zone in the typescript code. I’m also not aware of a way to get the current user’s time zone in a string variable in Workshop to send it to the function. But it still begs the question, why is Workshop automatically, without the option to change it, convert a timestamp from a function to the local time zone for the user? How do I disable this?
