Description jelle 2019-12-12 09:42:59 UTC 
Due to the use of __DATE__ in dustmite.d dtools cannot be made reproducible since the d compiler does not support SOURCE_DATE_EPOCH for which i made a bug for the D compiler. Removing __DATE__ from dustmite.d would be the easiest way to make dtools reproducible.

Comment 1 Mathias LANG 2020-04-14 10:42:54 UTC 
Raised a PR for 20444, this can be fixed once dtools are compiled with a compiler that supports it (tentatively 2.092.0).
Comment 2 Mathias LANG 2020-06-05 12:20:43 UTC 
Since __DATE__ now recognize SOURCE_DATE_EPOCH I believe this can be closed. This bug was mostly for packagers, who have control over which compilers are used for building, and LDC / DMD 2.092 have been released.
