You may also circumvent the problem by making sure your "online" OS is
configured to set its time via NTP once it gets access to the Internet,
this way, any problem with the hwclock will only impact the "boot".
Many routers face a similar problem because they don't have any hwclock,
so at the beginning of the boot they basically don't know what time it
is (it's arbitrarily initialized to some "dummy" value like 01-Jan-1970
or to some timestamp saved at some point in the past), and they only get
a valid time after they can connect to an NTP server.
