Is help2man to blame here?
help2man supports SOURCE_DATE_EPOCH and it does the right thing when it is set. --8<---------------cut here---------------start------------->8--- $ guix environment --ad-hoc r-minimal help2man $ help2man --include=R-3.4.0/doc/R.aux --no-info --output foo.1 R $ grep August foo.1 .TH R "1" "August 2017" "R version 3.4.0 (2017-04-21) -- "You Stupid Darkness"" "User Commands" $ SOURCE_DATE_EPOCH=0 help2man --include=R-3.4.0/doc/R.aux --no-info --output foo.1 R $ grep August foo.1 $ grep January foo.1 .TH R "1" "January 1970" "R version 3.4.0 (2017-04-21) -- "You Stupid Darkness"" "User Commands" --8<---------------cut here---------------end--------------->8--- Is SOURCE_DATE_EPOCH not set at the time help2man runs? “r-minimal” uses the gnu-build-system, which has a build phase set-SOURCE-DATE-EPOCH that sets SOURCE_DATE_EPOCH to 1. Where is this lost? -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
