He's talking about groups that are primarily email users only. Many don't want to worry about web access. In a situation like that, it makes sense to have the owner set an initial time zone default along with the other group defaults an owner can set.
In the case of a group with no set default, I like Glenn Glazer's thought about making it UTC since groups.io is worldwide. Many users are familiar with Zulu time already through the various disciplines they are involved with.
