Very funny indeed :).

Nice.

Dates are not easy to get right even in log2vis, let alone
vis2log...  If you really want to fix it, you can change the bidi
type of the '/' character in FriBidi sources and retry.
If you are using fribidi-0.10.15, you need to change the file
fribidi_tab_char_type_2.i, in the first table, third row, last
entry, it's "ES" right now.  Try changing it to "ET" and
recompile.

Humm, are you using 0.10.5 or 0.10.4?  With 0.10.5 the dates
should not get reordered as far as I understand.
