> __DATE__ and __TIME__ macros in C

So how do those work in these Debian reproducible builds? Do they outlaw those directives? Or do they set those based on something other than the current date and time? Or something else?

The toolchain (eg. compiler) reads the time from an environment variable if present, instead of the actual time. https://reproducible-builds.org/docs/source-date-epoch/
