DebianPts:asciidoc writes timestamps in HTML files it produces.

The date is based in the last modified date of the source file, but is sensible to the timezone.

= Workaround =

Prefix asciidoc command with TZ=UTC environment variable (while waiting for Bug:782294)

= Solution =

Either:
 * use [[https://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=patch.asciidoc.diff.txt;att=1;bug=777177|"-a footer-style=none"]] to entirely remove the timestamp - this didnt work for me when trying this with piuparts. In the end I used the [[https://anonscm.debian.org/cgit/piuparts/piuparts.git/commit/?id=e43ffd82af29f84d58ba85bf06900c1efb900603|:revdate suggestion]] from below from Jelmer.
 * wait for Bug:782294 . Then use --use-utc-timezone flag with asciidoc.
 * for manpages generated by a2x through docbook, consider adding ":revdate:" with a manual date (e.g. https://samba.org/~jelmer/socket-wrapper-reproducible.diff)
