Yes I do have an RTC. At that point in the logs dhcpcd hasn't started
so it must be from the RTC (although nothing seems to appear in the
logs from a quick glance). But I only mentioned it in passing because
otherwise it looked like the logs were from different dates despite
being from the same boot.

My script doesn't care about hostname. Hostname is set in
/etc/hostname but I don't know when that is read (nor care unless it's
a clue to why the script is running after networking starts despite my
efforts!
