Hi Dave
Our Windows TimesOwn Pro software clock does this
in a fashion.
TimesOwn Pro can be set to add additional "TimesOwn
Zone" registry zones with the correct TZ abbreviations into the
registry.
Windows can then select these alternative and
updated Time Zone rules to manage time from.
From TimesOwn Pro you can set out a group of time
zones for your trip and on arrival at each new destination simply select the PC
Time Zone from within TimesOwn Pro.
Is that of any interest?
Kind regards

Subject: Translate Windows timezone to
TZID?
I've been thinking about this problem for a while. Anyone
have
any thoughts?
Suppose you have a portable computer running
Microsoft Windows
(whatever version you dislike least) which you take with
you when
you travel. When you power it up and you're in a timezone
different from the one you last used it in, you use Windows'
Adjust
Date/Time dialogue to set the correct timezone.
Now Windows has bogus
names for the zones, like
"Dlt"="GMT Daylight Time"
"Std"="GMT Standard
Time"
"Dlt"="Hawaiian Daylight Time"
"Std"="Hawaiian Standard
Time"
which you can read out of the registry.
Suppose I want to get
the correct name of the time zone
(from which maybe I'll generate the
correct abbreviation).
So for GMT, the proper strings would be
"Greenwich Mean Time" for standard time, and there is no daylight
time. For Hawaii, I believe that's properly Hawaiian-Aleutian
Standard Time; again no daylight observance.
Is there a way anyone
can think of to map the incorrect
Windows text strings to correct text
strings algorithmically?
(Too bad Windows doesn't have the exemplar
city name in its
database of time zones.)
