I'm sorry, you have completely misunderstood the problem here. You are
storing data in the cloud, which means you're representing everything
with water. It is therefore fundamentally illogical to use any
temperature outside the range [273.15K, 373.15K], because otherwise
your cloud will freeze or boil, and either way, it'll crash badly.

Plus, converting to UTC? Puh-leeze. You should be using kilogram
meters per second.
