Last Published dated in API resources

[neil.s...@dootrix.com]

Is it possible to get the "Last Published" date in the Course or Blocks API resources? 

I'm trying to provide offline content via the API but I'm having to download all the web links and parse them before I store them on a device (lots of requests but needed). The issue is to check if anything is outdated I need to download and parse everything again to compare the offline and online data. If I could get the last published date of either the whole course or even of the individual blocks, that would be a lot more efficient than having to do 20+ network requests.

Thanks.
