Ok, I know this has been said a thousand times before, but fuck localization code.

Especially when you have to determine which badly-formatted timestamp is chronologically first.

BLEARGGHHH

localization isn't that hard if you're prepared for it and handle it as close to the frontend as possible, time should always be in UTC unless you are displaying it to a user (conversion should be done by the frontend), text is also easy if you use strings that provide context information internally and always translate them (translating from english is hard as some words have multiple meanings)
