Just say   $ /com/tz edt    or $ /com/tz pst  or whatevr, online.
No shutdown required.

This is true, but only if you use /com/date ...  Ooops.   /oj

Shut down is required for Unix because of the locality of the data, however 
the command does the change <you probably could get by with DM exit and go> 
to the underlying system clock.  Aegis environment users will get instant 
update without system shutdown.

Except the Apollo doesn't know about Hawaii Standard Time.  Depending
on the season, we are either 5 or 6 hours earlier than the east coast,
or GMT-10 hours. After much trial and error, I discovered an environment
variable that can be set in the node startup file which correctly
implements Hawaii Standard Time.

I think you are talking about the TZ variable (documented
in the Domain/IX manuals), only works in Domain/IX.
Also, /com/tz does not know about Hawaii but can be invoked
as /com/tz gmt_offset your_preferred_TZ_name and off you go
(documented in the help file).
People correcting other people would have to read manuals
before !
Apart from that, a real trouble for us is the fact that 
Domain/IX only knows about US rules for daylight saving time,
so we have to play around with TZ during the time IX thinks
it's DST and it is not. Sure, fixed in sr10 :-)
