The Modules/getbuildinfo.c file allows the use of
DATE and TIME macros to be defined via CFLAGS.

These vars, control the build date & time when the
interpreter is opened, and can be read via the
platform._sys_version() function.

So, a conversion from SOURCE_DATE_EPOCH to DATE & TIME
is required at build-time.

This is especially needed for platform._sys_version()
to work.
The installation of pip seems to rely on this.

The logic has been adapted from:
