So I have heard of an website called Hammertime, its basically where it can help out with 1 main issue that a lot of people face which is communication about the timing for people in different timezones! I suggest if person a needs to ask group a (1 of 6 people) to swap with them when they're in group d, they can use hammertime to get the time for them but then also have it set up to the other times for everyone else if they are in other timezones than the player who is asking so its easier to switch with them and without people asking what time it is in their timezone!

These can be done with timestamps (as they are rendered client side, it is rendered to your device time)
Like this <t:1750490000:F>
It also has the added benefit of separating the timezones from the users (timezones are definitely annoying 😄) - and just means the time you see is relevant for you
So someone could say 5 UTC <t: timestamp:F> and it'll show you what time it is for you
