Hi Phil, it looks like you've cracked it! Below, I have tested both setting the -filemodifydate from the -createdate and shifting the -filemodifydate back and forward one hour - all with DST enabled on my machine. As far as I can tell it looks perfect!

I understand that moving to a new version of Pearl is not to be taken lightly but in this case, it does seem to resolve the problem. Many thanks for all your help. Justin.. |
