<who> is player, all players, or a name. A named player may be offline: LuckPerms looks them up, makes the change and saves it.
The group has to exist in LuckPerms. A name it does not know is reported in the console and nothing changes.
Adding someone to a group they are already in replaces the old membership, so a new time limit takes the place of the old one.
Changes are saved by LuckPerms and, if it is set up for that, shared with your other servers.
