Dear Maintainer,

Extended support of SOURCE_DATE_EPOCH in TL2016 does a great job for
reproducibility [1]. However, setting a tool-specific environment
variable as SOURCE_DATE_EPOCH_TEX_PRIMITIVES from dpkg-buildpackage is
not possible.
I would suggest to set the default value of
SOURCE_DATE_EPOCH_TEX_PRIMITIVES to 1 instead of 0 in pdftex.

I think SOURCE_DATE_EPOCH is most often used to build reproducible
packages, and in this case the user always need
SOURCE_DATE_EPOCH_TEX_PRIMITIVES=1.
Also, SOURCE_DATE_EPOCH_TEX_PRIMITIVES=1 makes the dates in the
timestamps and in the document coherent.

Regards,
Alexis Bienvenüe.
