I know I can just cast to int, but is it ok to return an string for things that can only be numbers?
The date() and strftime() functions are expected to always return strings, no matter what the format string looks like. The same holds true for sprintf(), you wouldn't expect
sprintf("%d", 42)
to return an int, would you?
