Thank you very much hippo for advice.

For my rehabilitation i would like to say that i was a bit confused about this issue. I observed different behavior of my code on Win, Linux and Mac. And the various timestamp formats that one can pass to PDFs are a mess and put me over the edge. Perhaps i didn't see the basic problem and jumped to some wrong conclusions ;-).

For completeness:

"$mday is the day of the month and $mon the month in the range 0..11..."
karls-mac-mini:monks karl$ perl -E '$day=(localtime)[3]; say $day;'
13
karls-mac-mini:monks karl$ perl -E '$month=(localtime)[4]; say $month;
+'
5
karls-mac-mini:monks karl$ perl -E '$month=(localtime)[4]; say ++$mont
+h;'
6
karls-mac-mini:monks karl$ date +%m
06

D'oh!

Update: I just run my modified code on a PDF created on Win:

CreationDate was 06.06.2015 16:12 and now it is 06.06.2015 18:12.

This crap drives me insane.

Edit: Minor changes. Ain't no fun no more.

Best regards, Karl
