[API-users] how to check last date-time dataset was harvested?

Hi again.

Is there any way to use GBIF portal API to know the last date & time a certain resource was harvested by GBIF? (basically, to know if it has the latest info provided by the original source, or it could be outdated)

I suspect the info in this url but I don' know how to interpretate them all:

http://api.gbif.org/v1/dataset/df3eab30-0837-11d9-acb2-b8a03c50a862

I guess this is the IPT updated time:

"modified": "2017-02-16T22:07:41.127+0000"

¿Perhaps this is what I am looking for?

"machineTags":[{..."name":"crawl_attempt",..."created":"2017-01-05T12:07:12.525+0000"},...]

Thanks a lot David
