 Replying to [comment:6 tenzap]:
 > do you think setting this variable can be managed directly in the tool
 that calls the various phases of the portfile. This would make
 SOURCE_DATE_EPOCH available for every port ?

 What "tool" do you mean? The phases are run by MacPorts base. I am
 proposing that MacPorts base should set `SOURCE_DATE_EPOCH` in all phases
 of all ports.

 Haren has provided a PR implementing this:

 https://github.com/macports/macports-base/pull/274

 > May I suggest to add the revision number of the port (the value in the
 Portfile) to the timestamp in SOURCE_DATE_EPOCH? This would be like adding
 a few seconds to it and permit to represent in SOURCE_DATE_EPOCH that the
 Portfile changed. This is sort of analogous to the way debian does it
 (Debian uses the timestamp of the debian/changelog file).

 I don't know if that's a good idea. I don't see anything recommending
 doing that in the documentation link I posted at the top. I am not
 familiar with what Debian does or why it does it.
