Honor SOURCE_DATE_EPOCH

[roptat]

Hi,

I'm trying to package ocamlgraph for GuixSD, my distribution of choice. Like Debian and many others, we aim to have reproducible software. Ocamlgraph embeds the compilation date and therefore isn't reproducible. SOURCE_DATE_EPOCH is an environment variable that can be used by distributors to set a fixed compilation date and obtain a reproducible build. Its exact purpose is explained here: https://reproducible-builds.org/specs/source-date-epoch/.

With this change, Guix doesn't complain about non-reproducibility anymore, and it doesn't affect any user who don't care about reproducibility.

Thank you :)

Thanks for this patch; it makes sense.
(Actually, I don't even remember why I chose to have the compilation date as part of the information contained in ocamlgraph. I could simply remove it.)

I had to fix your patch using double quotes, as date sometimes uses parentheses (e.g. (UTC+0100)) that result in a syntax error. -- Jean-Christophe
