The ASF considers that the minimum time for a vote is 72 hours for a few reasons particularly:
(1) to allow the world to spin. People are in most time zones. (2) to allow for weekends. (3) to allow time for contributors who are not working full time on the project. Many projects use a 7 day vote. We just had 2 PIP votes called for 48 hours so this rule is worth reiterating! All the best, Dave Sent from my iPhone
