Here is a patch that should make AIX and IRIX more happy.
It changes all checks for tm_isdst to (tm_isdst > 0) and fixes
the expected horology file for AIX.
I just now realized, that the new expected file (while still bogous) is more correct
than the old one.
Thanks to Tom for mentioning that the hour should stay the same when subtracting
days from a timestamp.
Please apply.
