If a program accesses the BIOS clock directly, it may interpret this
differently than the OS does. The BIOS clock is likely set to local
time, not UTC.

True -- a program can also request UTC time, then apply the offset
incorrectly -- this is much more likely when going through either a
"programming language" library as he is, or an Open Source software
sub-system (as he is.)

If one machine reads a time from another where only one machine has been
patched or one has been set to the wrong timezone there could be a
discrepancy, as well.

No. Why would that happen? If the timezone update has or has not been
applied correctly this is NOT going to affect the time there UNLESS
someone SET the time wrong in a misguided effort to make the time
"look right".

When the zone cannot be set correct (PDA or some such) then the time
zone should be altered to make it display correctly.

I actually have a very cool bedroom clock that RADIO syncs with a
UT source and displays on the ceiling for reading in the dark, but it
has no (correct) DST settings and we have to adjust the display time
by setting the timezone to an adjacent zone.
