usage: mpdexit mpdid
mpdid may be obtained via mpdtrace -l (or may be "localmpd")
Causes a single mpd to exit (and thus exit the ring).
Note that this may cause other mpds to become 'isolated' if they
entered the ring through the exiting one.
ctime(seconds) -> string
Convert a time in seconds since the Epoch to a string in local time.
This is equivalent to asctime(localtime(seconds)). When the time tuple is
not present, current time as returned by localtime() is used.
