Timezones are a convention between countries so people can know what
time it is in other countries or cities within their own country.

Hardware time is held in a hardware clock on the motherboard, (resitors,
capacitors, transistors, etc), and runs off the bios battery.
System time is held in a software clock and can be easily programmed,
but only runs when the system is running.
When the system boots the system clock has forgotton the time, and
resets itself from the hardware clock (UTC), and then adjusts itself to
the local offset by reading the timezone file that is identified as
localtime, (this adjustment includes daylight saving if necessary).
Adjusting the hardware clock is best done with a package, developed
especially for that purpose, (my favorite is ntpdate).

No idea about Solaris, got enuff trouble with Linux.
