That clock is only read on startup and set on shutdown or if directed to
by the user with the hwclock command.  Once the system boots, a clock on
the CPU itself is the only one Linux cares about for time of day.  If
NTP is enabled, it uses other sources on the local net or Internet to
help keep the CPU clock rate correct.

So dead motherboard "hardware clock" battery wouldn't explain issues
with the CPU "system clock".
