It looks to me like 8.1 thinks SST is Swedish Summer Time (GMT+2),
so for your purposes that probably only "works" for rather small
values of "works". 8.1 doesn't know the SGT timezone abbreviation
at all.

In 8.1 there is no way to change this behavior short of compiling
your own version with a patched timezone abbreviations table.
You might consider updating to 8.2 or later, in which versions
the set of recognized TZ abbreviations is user-configurable.

FWIW, 8.4 and beyond will have SGT = GMT-8 in the default abbreviation
list.
