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?

Subject: Translate Windows timezone to TZID?
I've been thinking about this problem for a while. Anyone have
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.)
