Since this function only accepts integer timestamps the u format character is only useful when using the date_format() function with user based timestamps created with date_create() . timestamp
The optional timestamp parameter is an integer Unix timestamp that defaults to the current local time if a timestamp is not given. In other words, it defaults to the value of time() .
