Support for Ubuntu 18

Dear Dave,

I have just added explicit build instructions for Ubuntu 18.04 in the Orthanc distribution (those are just an adapted version of the instructions for Ubuntu 16.04):
https://bitbucket.org/sjodogne/orthanc/commits/4e34fd3e226a63161b25feade8db444c716603ce

These build instructions have been validated in a Docker environment started as follows:

$ docker run --rm -t -i ubuntu:18.04

HTH,
Sébastien-

Sebastien,
I appreciate the added notes, and to confirm: when I build the product from source, everything works as expected, including setting the tzdata to UTC. However, I’m hoping to deploy a system that doesn’t require every server to have to build it’s own binaries from source, which is why I was attempting to use the pre-compiled binaries from lsb.orthanc-server.com. It’s when I use those the problems arise with “Etc/” … are you able to re-produce the problem I’ve outlined?

Please keep discussing the UTC-related problem in the original thread:
