Build me a PHP date and time helper library that makes working with DateTime much easier in everyday apps. I want it to feel simple and fluent, so I can get the current time, add and subtract dates, compare moments, and format dates in standard ways without a lot of boilerplate. It should handle timezones cleanly, support setting a fake current time for tests, and make relative differences easy to read, like “2 minutes ago” or “from now.”

It would be great if it also supports lots of locales so dates can be shown in different languages and regional formats. Please make it usable with Composer, and include clear examples and tests so it’s easy to trust and try out. If you need to check current docs or behavior for the latest PHP date handling, look it up online first.
