Remember that we are talking about installing base. There aren't the
facilities for apt at this point in the installation.

This could work. The trouble is that we need to set it in CMOS, too.
This isn't a problem with getting the correct date. I don't believe
that the clocks must be exactly the same. Thus, netdate is one method
for getting the date, but it seems more appropriate to make it a
general change to setup where the user can set the system clock.
