A detail but, in an international system like the Internet, never use
local time zones. People may not know them, and some time zones
acronyms are ambiguous. Always use UTC. (Or TAI for über-geeks.)

Even worse since you don't know how old is the message. (It's the same
problem with capsules announcing "this will be done next week" when
the text does not mention the date where it was written. HTTP has the
- almost useless in practice - Last-Modified: but Gemini must relies
on the text.)
