The patch behaves well on Linux (with GNU tools), but not on Solaris for
example.

+	thisyear="$(date +%Y)"

This should be changed to:

	thisyear="`date +%Y`"

Why is this necessary:

+	$XAR tv "$1" | sed 's,^,-,;s, , 1 ,;s,/, ,' | sed -e "s/\(.\?\)\([0-2][0-9]\:[0-5][0-9] \)\(${thisyear} \)\(.*\)/\1\2\4/" | sed -e "s/\(.\?\)\([0-2][0-9]\:[0-5][0-9] \)\([0-2][0-9][0-9][0-9] \)\(.*\)/\1\3\4/"
                                                                ^^^^^^^

The \? is GNU extension and I don't really understand why that construct
is necessary (I am not a regex guru though) so can you explain ?

I agree. Determining the date format could be achieved but it is not a
trivial task and I am not really sure that it is so important after all.
