DST adjustment is handled by the C library as the kernel core time
is in seconds since a fixed point. The system also knows about
handling DST shifts in the CMOS clock and will correct for this
except for PIIX4 in certain years (hardware errata)

Indeed. A Linux system supports multiple users in different timezones
with different daylight saving rules - at the same time.
