Narrative:

Aircraft blocked out 1 minute early. We had received a revised release time during preflight checks. I had calculated the 15 minutes. At [one minute before the release time] I called for pushback clearance with ops; at the same time the captain misunderstood what I was doing and told the ground crew we were ready to push back.
