BrenekH: Modify the flake reproducible image dates section to use a snippet which doesn't exclude the the time of the commit. The original snippet intentionally cut the time so the `date` command would accept the input of `self.lastModifiedDate`. By using `self.lastModified` (seconds since epoch of commit) and prepending "@", the date command can interpret the full datetime and embed it into the resulting image.

Rootless containers are not able to bind ports from 0 to 1023 as such port can only be used by privileged users. This problem can be solved by using port forwarding.

	Assume you'd like a rootless container to make use of ports 53 (DNS; TPC and UDP) and 80 (web; TCP). We may force the container to use port 8000 while the firewall is instructed for forward traffic from port 80 to 8000. Same logic applies for port 53.
