Post not sent to the Slack channel

https://stackoverflow.com/questions/57965526/how-to-skip-errors-in-a-loop-for-julia

This question doesn't appear in the slack. Either the tag was edited, or there was a weird time issue. (edge case related to the time calculation).

Start with the linked Stack Overflow question and inspect the bot's handling of edited tags and time calculation around that post. Reproduce why it was omitted from Slack and trace the relevant edge case; done means the post is delivered correctly without breaking the existing filtering behavior.
