X-Git-Tag: lucaceresoli/bug-15201-perf-libtraceevent-missing~19192
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=225a7156d1fb2fbffadf38e4f4e491f053358082;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

package_rpm.bbclass: clamp timestamps

Improve binary reproducibility of RPM packages.
Ensure timestamps in RPM packages are not later than the value
of SOURCE_DATE_EPOCH. If SOURCE_DATE_EPOCH is not set,
timestamps are not clamped.
