Shouldn't pull be able to attach transaction time and valid time of the document?

[coadan]

I know that I can do an entity-history query, but isn't it a common requirement in application to look at the last valid time of a pulled entity? Would it be possible to add an option to the pull-interface for attaching the tx-time and valid-time to the pulled document like xt/valid-time xt/tx-time or something?

I would have reservations about returning the times within the document maps, as no other APIs do anything like that currently, although for the Clojure API it could be quite elegant to attach the times to the maps via metadata. In the meantime, short of designing and implementing a solution that works within pull and is cohesive with everything else, you can retrieve the information within the main query if desired, e.g. https://gist.github.com/refset/8439ceebf3c1f08c614b0c818266a140

Fundamentally I think you're right though - that users do want convenient access to this information.
