Yes, well all I can say is that after a lot of frustration like yours,
since I hit on the TZ setting format above it seems to work OK here! In
Yarn/2 using OS/2 Warp 4 it's giving me a 13-hour correction right now,
as it should. And if I change the system date to (say) 20 June 1997 it
changes the correction to 12 hours, also as it should. I shall await
the end of March with interest to see if it does its thing without
intervention!
I stand to be corrected, but by way of a pretty broad interpretation of
the information in Norbert Dey's TIME868 timesetter program help file
it seems possible that Warp itself understands the RFC 868 standard for
the TZ variable, but that Yarn/2 only knows about an older form.
