Staging tags are created with Date.today, which is the computer's date.
This means someone in Singapore might deploy on July 20th at 2am (July 19 6pm UTC), creating a staging tag of staging-2017-07-20-xxx, and later (chronologically) someone in New York might deploy on July 19th at 6pm (July 19 10pm UTC), creating a staging tag of staging-2017-07-19-xxx. When deploying this will cause issues because Capistrano sees the earlier deploy from Singapore as the latest staging tag.
