Yes, that's it. Why do you worry of not having a BIOS option for GMT ? I
guess that you don't have an option for your TIMEZONE neither do you ? As
far as BIOS is concerned, GMT is a setting as any other of the clock (unless
your BIOS propose an option for DST : I never use it because it causes
problems with any OS sufficiently evolued - anything other than DOS seems to
take care of DST already...)

according to the help you can get during make (|x|menu)config this one
should be disabled unless you have some specific laptop.

IMHO you should enable this one not only for power saving but to avoid
overheating of your proc.

To me this seems correct but wait for the advices of people using laptop
wich is not my case

Have a look in your /etc/adjtime file, the first value of the first line
should be in the neighboroud (spelling ???) of zero (being out of [-30;30]
is unusual). Having here a value of 720 would make you loose 3 hours in 15
days. It has nothing to do with BIOS or APM option...

Same thing here for slink and hamm. It is coherent with your choices
regarding APM unless potato uses an other way to set this point.
