I needed to determine if it was possible to:
1. Detect when a new post is submitted via client side
Reason: We do a lot of support here. We do not want “stale” cases to go unanswered or slip through the cracks.
==\> If specific poster != x set topic timer on a specific topic based on this change and set it to a specific user
It a long shot and I have a feeling this functionality will require a full plugin however I wanted to determine if this was the case.
I guess I am more directly trying to find out if I can even detect a post submission and if I can update the timer via an api call to the topic. I can figure out the rest myself if I can confirm this is possible and where this is documented.

There are webhooks sent when a new topic or post is created. They could probably get you the information you need. See: [Configure webhooks that trigger on Discourse events to integrate with external services](https://meta.discourse.org/t/setting-up-webhooks/49045).

That is excellent. Just what was needed for the submission. Last thing is there a way to update the time on a topic? I can see in the app docs how to create a topic with a timer but can this timer be updated dynamically?

There is also [update a topic timestamp](http://docs.discourse.org/#tag/Topics%2Fpaths%2F~1t~1%7Bid%7D~1change-timestamp%2Fput), which might be what you want.
