How would you write this function

I'm wondering how experienced go devs would write the following simple function: https://go.dev/play/p/MZeKEWlmz0r. I'm mainly confused about the error handling if the error can come from multiple sources.

you would want to check if err != nil in main too

[safe dagger]

that seems fine but nitpick
warp your errors

return TimeFormat{}, fmt.Errortf("error parsing minutes: %w", err)

that lets the consumer knows WHY what went wrong not just "error parsing int"
