It bothers in general me when people use words like "everyone."
There is a tendency on this forum to think that your FS represents the feeling of all players.
EVERYONE online or reliant on business or government, as nearly everyone also is, uses UTC based systems.
Given that GMT was deprecated in the early 1970's and replaced with UTC then, use of "everyone" in that context which references world legal and technical official standards, and systems that nearly universally (universally for servers and most serious net functions) calibrate to that via NTP, at least in carefully selected uses and stipulated conditions, such language can be precise and accurate.
People using the term "GMT" in the last several decades also cause confusion over the meaning of BST, or BS-Time.
France won the fight with England 50 years ago, in that French as a legal spec for that primary time standard results in UTC spelled out translating to "Coordinated Universal Time". Urban Dictionary might suggest a variant called "Coordinated Universal Network Time". But, blame stodgy Brits, and France, for England retaining GMT as their term for UTC-0 as standard time there in winter, versus BST as British Summer Time springing forward an hour. How wonderfully clear to munge a deprecated standard into a local time zone ongoing name. Too bad no one was around to musckster them when needed?
When Inno CM's have copied and pasted notices about events in CEST in winter, it's clear they have little functional literacy in job duties, not that the EU Parliament didn't cause major headaches bumbling around and even implementing and then withdrawing one proposal to scramble EU Summer Time by order of law there.
Inno's operation of a global game based on Hamburg local time, whether CET (UTC+1) or CEST (UTC+2), further scramble things in that while both are usually 6 hours ahead of EST or EDT, the dates of seasonal shift change, such that there's a 1-3 week offset period, and a history of staff or server admins down the street making changes that end up shifted an hour after that interlude, as if Inno needs to test HR for their capacity to test new hires for basic functional literacy in that key issue of international business and tech.
Everyone competent to be a functional adult in our global village has those functional literacies.
What does that imply, given the history of hostile anti-intellectualism movements, or the fact that very few people have any clue how complex time systems are, and why? (Note that includes the idiot Italian physicists who published a report claiming to swap photons with CERN faster than C, because they failed to grasp accurate use of precision GIS time standards.) Maybe they were trying to misapply BS-Time? ;-)
