This matches my understanding when I looked at ntpdate-debian with a similar issue, though I haven't tried to verify this for certain.

I wonder what the intention of ntpdate-debian is in this case. Does it do what it does because we don't want NTP to be set from DHCP by default?

Is the reason you're facing this problem because your hardware doesn't have an RTC, or because system doesn't use the RTC at boot time, and is stuck at epoch? Fixing NTP from DHCP should certainly fix the issue, but why isn't the RTC being set correctly at install time and read correctly at boot time? I recently had a case where I fixed this in the kernel, and then the NTP DHCP situation didn't matter.
