+This allows us to put /usr/share/groff/tmac at the end of groff's macro
+path in Debian.
+
+This uses GNU-make-specific code, so it may not be forwardable in its
+current state.  A more upstreamable approach might be to add a --with-*

+Subject: Display time from SOURCE_DATE_EPOCH in UTC.
+
+The semantics imposed in 1.23.0 are unsuitable for use with
+reproducible-builds harnesses, since those specifically want to vary the
+TZ environment variable to shake out other problems in build systems.
+However, my patch that Debian has been carrying for a while is
+unsuitable for general use, since most people expect the time displayed
+in output to use local time.
+
+A viable compromise seems to be to force UTC _only_ when
+SOURCE_DATE_EPOCH is set.  That will keep reproducible-builds harnesses
+working with no extra effort, while also preserving the expected
+behaviour for typical users of groff that don't go out of their way to
+set that environment variable.
+
+As a bonus, this corrects the behaviour of gropdf when the local offset
+from UTC is not a whole number of hours.
+
+* src/include/curtime.h (current_time): Return a `struct tm *`.
+  Document behaviour.
+* src/libs/libgroff/curtime.cpp (current_time): If SOURCE_DATE_EPOCH is
+  set, return the overridden time after passing it through `gmtime`.
+  Otherwise, pass the current time through `localtime`.
+
+* src/devices/grohtml/post-html.cpp (html_printer::do_file_components,
+  html_printer::~html_printer):
+* src/devices/grops/ps.cpp (ps_printer::~ps_printer):
+* src/roff/troff/input.cpp (init_registers): Adjust to new
+  `current_time` signature.
+
+* src/devices/gropdf/gropdf.pl: If SOURCE_DATE_EPOCH is set, return the
+  overridden time after passing it through `gmtime`.  Otherwise, pass
+  the current time through `localtime`.
+  (PDFDate): Fix output in the case where the local offset from UTC is
+  not a whole number of hours.  (Previously, the minutes offset field
+  was always set to zero.)
