Is there a quick way to get from a datomic t value to a java.util.DateTime representing the (approximate) time that it occurred? I could swear I saw a function or something at one time, but now I can't find it

(->> t d/t->tx (d/entity db ) :db/txInstant)

java.util.DateTime? you mean java.util.Date?

Er, yes

Ah, I had forgotten about :db/txInstant. Thanks @favila!
