That looks like you're "sign-extending" the 16-bit value to a 32-bit value. The
original timezone value would be 0xff8a, which is -118 (decimal). The SMB
specification states:

        "If the zone is in the range -720 to +720, it represents the
        number of minutes east or west of UT. Values in this range
        should only be used for time zones not otherwise represented
        here."

-118 is in the range of -720 to +720, so the timezone is 118 minutes west of
UT, typically displayed as UTC-1:58 (which is a pretty odd timezone). :-)

There's a routine to display a string representation of a timezone in the
SMBLIB:
http://cvs.synchro.net/cgi-bin/viewcvs.cgi/*checkout*/src/smblib/smbstr.c
(see function smb_zonestr).
