In my humble opinion, time stamps are very good for debugging
but might be slightly too verbose for average users.  Additionally
it could reduce readability of log files.

I think a kind of log level (verbosity level) is desired so
that XWiin will print time stamps if -verbose or -debug flag
is specified.  However I can't contribute right now so I honor
implementor's choice.
