But... why?
Having used strftime in many other languages (shell, ruby, python, c),
Go's date formatting can be frustratingly different — frustrating mostly because
we're too lazy to learn a new date format. This site was built to allow the
laziness to continue.
If you really need strftime functionality, there are a few
open source alternatives.
