All financial systems don't care about time.

Prety much all financial transactions are settled with a given date, not instantly. Go sell some stocks, it takes 2 days to actually settle. (May be hidden by your provider, but that how it works).

For that matter, the ultimate in BASE for financial transactions is the humble check.

That is a great example of "money out" that will only be settled at some time in the future.

There is a reason there is this notion of a "business day" and re-processing transactions that arrived out of order.

The deeper problem isnt global clocks or even strict consistency, it’s the assumption that synchronous coordination is the default mechanism for correctness.That’s the real Newtonian mindset, a belief that serialization must happen before progress is allowed. Synchronous coordination can enforce correctness, but it should not be the only mechanism to achieve it. Physics actually teaches the opposite assumption, time is relative and local, not globally ordered. Yet traditional databases were designed as if absolute time and global serialization were fundamental laws, rather than conveniences.We treat global coordination as inevitable when it’s really just a historical design choice, not a requirement for correctness.
