:I still don't understand what you're saying about programs not liking
:the time zone changing from under them. Typically any program which
:uses time zones will access /etc/timezone once only. It remains stuck
:in that time zone. That may be a nuisance (I find it annoying with
:syslogd, for example, but kill -1 will fix that). I frequently fly
:transpacific without rebooting, but change through all time zones
:where I stop over. I've never had any problems.

I think you missed the original article. The idea was to try to
have a running programming automatically detect the timezone change
and adjust its internal state accordingly. Doing that automatically
without the programming knowing isn't a good idea.
Adding code to sendmail, syslogd, cron, etc... to detect the change
at a safe point, on the otherhand, might be interesting. But,
ultimately, I think it would be kind of a waste of programming
hours to do.
