Comment (by tenzap):

 @ryandesign, 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 ?

 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).
