My (ill-founded?) reasoning went like this:
* -L is for if "the real time clock is in local time rather than GMT"
* my bios rtc is not set in local time, it is in UTC time
* therefore, I do not want the -L switch passed to aux/timesync

I do not know. I'll try this though.
Approximately how long is 'some time'? (so I know how long to wait)

I'll look into this also, thanks for the suggestion.

Please see below. My experience is indicating a different reality,
or I'm still not interpreting my experience correctly.
Clearly no one's under any obligation to help me see the light, but
I do value the time and effort spent attempting to do so!
And I realize that it's entirely possible I'm just incurably chrono-impaired.

Yes I was aware of this, although I did it more naively (cp
/adm/timezone/local /env/timezone).
My point though is that yes, it makes the timezone change take
effect immediately - and it likewise causes the 'creation time after
last write time' /dev/kprint's to appear instantly as well...
And yet, timezone does not affect venti?

Good to know - thank you.
