You TZ variable should be a combination of the first two, except that
timezones are backwards (my theory is that TZ was invented in the
US, and the US did not want to be negative). Also, specifying the
minutes is optional, and I think it is implementation dependant
whether a colon is used (at least on Windows where most
implementations do not follow the POSIX spec for TZ)

so TZ=HST10 should give you the correct times now.

You can also add the daylight time name to the end of that (if Hawaii
has daylight time) to get automatic daylight savings. Since you are in
the US this probably works properly. I know it doesn't work in a lot
of software in the southern hemisphere due to incorrect assumptions in
Microsoft's (and other vendors') C runtime library, and is often a
week out with the changeover date in Europe for the same reason.
