Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
schism could not be built reproducibly.

This is because it embedded the timestamp of a source file via the
__TIMESTAMP__ macro. Unlike __DATE__ and __TIME__, this macro is not
automatically adjusted to SOURCE_DATE_EPOCH.

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
schism could not be built reproducibly again.

I can't tell from the Git history, but it looks like the patch was
disabled for some reason, perhaps after it no longer applied?

A patch correcting both issues is attached.
