Is there a way to export ES indices from a time range? i.e. 1:00 PM - 2:00PM? I want to be able to export this range and send it another ES instance.

There's no built-in mechanism for this. Unless there's an existing program that can do this ([Elasticsearch Knapsack](https://github.com/jprante/elasticsearch-knapsack) comes to mind) you'll have to write something yourself. It should be quite easy with e.g. [elasticsearch-py](https://elasticsearch-py.readthedocs.org/en/master/).

Using the python client there is an efficient "reindex" api[1] that can take a query as criteria to subset the data

You can also use Logstash for this via [this](https://gist.github.com/markwalkom/8a7201e3f6ea4354ae06) method.
There is also [snapshot & restore](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html).
