I think most of the snippets are trivial messing with the gcc __DATE__ and __TIME__ macros. I dug into GCC source code the other day and found this commit: https://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommitdiff;h=3Ddfa5c0d3f3e23e4fdb1= 4857a42de376d9ff8601c Apparently gcc will respect SOURCE_DATE_EPOCH in these functions from version 7 onwards. We could consider backporting it. Just thought I'd share, I'm sure this was discussed at the summit :-) --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEu7At3yzq9qgNHeZDoqBt8qM6VPoFAlh4AK4ACgkQoqBt8qM6 VPrx5Qf9FedVMXqq1E0y81jqQt8v6RlVt8f+trXsEO9ZX5Am8yT21odPGz5ZNXEG m+zS139KbmvoAMI6S9nrg1tUNrFrlaZDyqhLRilDMsTimj1eA7/qltKZQe7rfd9x WH8qlM1ongPtHKqHQ/ERZOC8APSBsATHN25CvcZh3Rpq4ouR1SZfSPs1ODrusDMH FsjZkzg+vYvo4ai2BEXd9oW+6djYgh7bkOKG9embFfpWLs5CgVU+bxz9olU4syUe 5avxrHVob0PJcbipsGAq2uH4FP3iIcvhOSG+93bpA79yaymdk4B34Li1fOO7Uf+V ZdmwEKvBfzTvXuWdM4Cpis3IMff6Lg== =4Zyk -----END PGP SIGNATURE----- --=-=-=--
