This is now fixed with commit 174fbd5f3b2f286cf06e58787853db6b8f0f5b35. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net

Simple: R simply doesn’t use our help2man. It comes with tools/help2man.pl, which does not respect SOURCE_DATE_EPOCH. Overwriting the HELP2MAN variable causes the tests to fail, so I need to investigate how these versions differ. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net

bug#28241: man page in r-minimal contains timestamp
The compressed man page at “share/man/man1/R.1.gz” provided by r-minimal contains a time-dependent string. Comparing the uncompressed man pages built at different times on different machines shows me this: --8<---cut here---start->8--- diff /tmp/berlin/share/man/man1/R.1 /tmp/hydra/share/man/man1/R.1 2c2 < .TH R "1" "July 2017" "R 3.4.0" FSF --- > .TH R "1" "May 2017" "R 3.4.0" FSF --8<---cut here---end--->8--- The man page is created with a rule in “doc/Makefile.in”: @$(HELP2MAN) --include=$(srcdir)/R.aux --no-info --output=R.1 \ --name="a language for data analysis and graphics" \ $(top_builddir)/bin/R “doc/R.aux” does not contain a timestamp, nor does the help output of R itself. Is help2man to blame here? -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
