missing posts by crawling to an exact date

Hi,

in our use case we want to get all the new posts that chanced since the last visit. Therefor we use a timestamp to check what’s new.

In some cases we miss posts with this method. Maybe this is because the posts have something like a “moderation gap” that provides the posts some seconds later to the API than their postdate?

As a workaround we add 60 seconds to our check date. This results in more request but lower loss rate.

Is there a way to get all posts without an overlap?

Thanks,

Martin
