System Time Settings

This is a more generic question, prompted by the discussion about the
Indiana conversion to DST.

My system is in California, which is Pacific Time.  I see three
available choices ...

QN0800PST - DST checked
QN0800U - DST checked
QN0800UTCS - No Daylight Saving Time

All three are at UTC -8:00.  The first two appear to be exactly the
same, except for the msg descriptions used to get the time
descriptions.  Are they, or am I missing something?

My system is currently set to the last (no DST) zone.  I have been
managing the DST change automatically using a program from Midrange
Computing magazine.  I gather that I can eliminate the use of that
program if I change the system time zone to one of the DST enabled
zones.

I also gather than I can use the TCP/IP SNTP service to synch my
system time automatically to an internet time server, and that the
system knows how to make the DST change and SNTP changes work together
so that the time stays correct.

Am I correct?
