Any update on the time-libraries? Would need [a light weight time abstraction for malli](https://github.com/metosin/malli/issues/49), supporting Clojure/Script. Something small and simple, compatible with `java.time`. Could be just a standalone `malli.time` namespace, but could be a 3rd party lib, if such exists. In JSON Schema, there are only `date-time`, `date` and `time`.

Requirements:

- basic types (java.time & ??? for cljs)
- type and range validation
- parsing from strings (+ formats)
- small js bundle size
