update_time does not seem to update time

I am trying to update the time of posts following the documentation, but the interface shows no change in time.
For example, iterating over some rows row:

dt_obj = datetime.datetime.strptime(row['dt'], "%Y-%m-%d %H:%M:%S %Z")

bookmark = pb.posts.get(url = row['url'])['posts'][0]
print(bookmark, bookmark.time) # -> shows 2020-07-15 19:00:50

bookmark.time = dt_obj
print(bookmark.time) # -> shows 2016-09-19 03:44:42

bookmark.save(update_time=True)

But the website still says created 15min ago. Thank you for any pointers and for making the wrapper.

I've had a similar problem trying to fix the times from an instapaper-exports.csv import.

I noticed that the source doesn't convert the datetime back into a ISO-javascript timestring. I tried this, but it too does not seem to have an effect.
