Subject: Force mtime for tar used in container config md5sums
X-Git-Tag: opnfv-6.0.0~456^2
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=f739fd0ccfb878e88672feb3fb4eb3a575461604;p=apex-tripleo-heat-templates.git

Force mtime for tar used in container config md5sums

The checksum is changing each run because the mtime is different, so force
a specific date such that we only compare the directory contents.
