Use the canonical timezone for Mountain Time

[stefanor]

The main tzdata database only contains the canonical names, abbreviations may not be installed. In Debian they're packaged in the tzdata-legacy package.

Hi Stefano,
Thank you very kindly for this fix. I have released a new version of fluids 1.0.27, with the fix.
I recently added some CI to run the tests of fluids on other CPU architectures through QEMU specifically because of another time some tests had failed in debian with minor numerical differences.
I will continue doing my best to keep the tests in fluids high quality and reliable. Please do not hesitate to reach out if there are any issues in the future.
Sincerely,
Caleb

Thank you.

It looks like it just missed the tag, but I see it in the changelog for 1.0.27.

Thanks for catching that! Yes it was a bit odd getting this PR at the same time as I was in the middle of releasing. I've corrected which commit had the tag to the latest in master, with the changelog update commit.
