This changes the samples for port, volume_connector, and volume_target so that the updated_at and created_at values are constant times, similar to the node and chassis. This patch makes the build of Ironic reproducible. If you don't know about reproducible build, please read on: https://wiki.debian.org/ReproducibleBuilds https://wiki.debian.org/ReproducibleBuilds/About Debian has SOURCE_DATE_EPOCH set according to the last date of debian/changelog, which makes it so that the time is constant, and the build becomes reproducible. Change-Id: I302609bf53659e33e89cae223336a453052a5745 Co-Authored-By: Ruby Loo <ruby.loo@intel.com>
