In almost all cases, you want single quotes around the printf format
specifier. This allows you to put all that weird punctuation inside
it without having to worry about what gets expanded, which backslashes
are removed prematurely, what gets treated as a shell metacharacter, etc.
unicorn:~$ printf '%(%Y-%m-%d %H:%M:%S)T\n' -1
