>Description:
Found in the debian MKREPRO builds for NetBSD:
Quite a number of PostScript files are built and gzipped, and they do
include timestamps -- once inside the .ps file, and a second one in the
.gz file.
This makes consecutive builds of the same tree differ.
>How-To-Repeat:
Look at /usr/share/doc, e.g. papers/mckusick84-ffs/mckusick84-ffs.ps.gz,
or morris*/*ps.gz or psd/*ps.gz, or reference/ref1/*/*.ps.gz, but at first glance
basically every *.ps.gz file there.
>Fix:
Do not include a
%%CreationDate:
in the PostScript files, remove it, or set it to a particular date,
like the date of the last change to the inputs, or the value of a
new MKREPROTIMESTAMP variable.

Then, find a similar solution for the time stamps inside the gzip(1)
headers of the .gz files.
