and make host and user overridable in order to make builds reproducible. See https://reproducible-builds.org/ for why this is good and https://reproducible-builds.org/specs/source-date-epoch/ for the definition of this variable. Also switch to UTC to be independent of timezone. Also use ISO 8601 date format to be easier to parse. This is similar toc9f4022783anddf82ec8fe7which was lost in the move away from automake. Note: This date call is designed to work with different flavors of date (GNU, BSD and others). If only GNU (Linux) support is needed, the patch can be simplified. This PR was done while working on reproducible builds for openSUSE. Type: fix Change-Id: If4cab12320e6b5fcb1f2842fac5d745b33b01ed7 Signed-off-by: Bernhard M. Wiedemann <bwiedemann@suse.de>
