[kmod]

I hear this from tech people, but hft people are happily humming along with highly-synchronized clocks (mifid ii requires clocks to be synchronized to 100us). I wouldn't say it's "easy" but apparently if you need it then you do it and it's not that bad.

That only applies if the clocks are within 1ms of each other, so around 100 miles (or equivalently: within a single cloud region), and only came in to force in 2014.

The bound that Spanner-likes keep is ~3ms for datacenters across continents, and that was in 2012.
