Sorry if I'm missing something, but what would promiscuous mode do in this age, exactly? I personally haven't seen a hub in at least a decade, and on a switched network, is there any difference?

Yes, there's tons of non-unicast traffic: ARP requests, spanning tree, various UDP broadcast packets, etc...

The NIC would receive broadcast traffic regardless of whether promiscuous mode is enabled, wouldn't it?

Broadcast packets are received in non-promiscuous mode, obviously. Otherwise none of this would work without it.

Yes, you are correct.. I was more commenting that the "stray" network packets could still be used for timing.
