how does one simply give the assistant the current time haha

Create a custom function tool that retrieves the time and integrate it into your assistant’s configuration, allowing it to respond with the current time when requested..

ok im using https://timeapi.io/swagger/index.html for that im currently doing everything in ui btw is there a way to do a simple GET requst with the custom function? It's trying POST idk why

Yes, by configuring the tool with the API URL, parsing the response, and integrating it into your assistant’s workflow.
