I was the first to cast a vote-to-close for datetime2 define dates "globally" outside of \begin{document}datetime2 define dates "globally" outside of \begin{document} (see the post timelinepost timeline) as I am a firm believer that a duplicate question is defined by the answer 99 times out of 100. I noted the OP posting "The answer is herehere" as the lead-in to the answer, visited the link and saw similarities, so I voted to close. I should have read the differences in the answers more closely...
No harm seems to have come from it as it has been re-opened - something completely in line with the network functionality and community behaviour.
