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.
- joshuamorton 3y ago> (mifid ii requires clocks to be synchronized to 100us) 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.
