You could already have something like:
log { source { !debug; all; } destination { file "ircd.%Y-%m-%d.log"; } }
But now you can also have:
log { source { !debug; all; } destination { file "%Y-%m-%d/ircd.log"; } }
This is especially useful if you output to multiple log files and then
want them grouped by date in a directory.
