Time zone offset and daylight saving

I don't seem to be able to correctly calculate the time offset between
two time zones when daylight saving is in effect. The code below
demonstrates that Ruby knows about daylight saving, but I get the wrong
answer when I calculate the offset.

BTW, yes, I know I can use Time#utc_offset, but I believe that depends
on me actually being in that timezone. I'm looking for a way to
calculate the offset between two arbitrary timezones, neither of which
is my local timezone.

Thanks for any help.
