That's a great example. What if I'm working in a embedded system with limited memory and I need to shave off a few kilobytes? What if time zones don't matter for my implementation, say I make a timer app and the only thing that matters is the delta between two times?

There are things that I think rise close to the level of best practices. For example your password hash comparison function should probably run in constant time, but a linter is never going to pick up on something like that.
