SOURCE_DATE_EPOCH is used to define the date/epoch and is evaluated
for pdf output etc
SOURCE_DATE_EPOCH_FIXUP_TEX_PRIMITIVES = 0|1
if non-0 then also \today is fixed.

Agreed.  That's what I meant to propose yesterday, but confused myself
as I was writing.

Thanks for the draft patch.  I'll look at it.  It will take far more
time to test and document than anything else :(.  -k
