The source date epoch is the only reproducible date close to the actual build date. It can be used for tooling like the firmware wizard to show the image age. Signed-off-by: Paul Spooren <mail@aparcar.org> (cherry picked from commit 165f0b00cdd2f763c1d478c2f58c535fc19b13bd) [store source_date_epoch as integer] Signed-off-by: Paul Spooren <mail@aparcar.org>
