I often see time.Parse as a common complaint - but my code is much more readable when I can see what the date format looks like, rather than trying to interpret the cryptic syntax which differs from language to language.
It's sure not perfect, and it's impossible to please everyone but I think it was worth the experiment.
I've found some legitimate bugs[1] in simple functions that don't give me a ton of confidence in it either.
Personally I find the standard libraries in the likes of Python and .NET Core much more comprehensive, intuitive, and reliable.
