Narrative:
Originally our day was scheduled at 8 hour 10 minute block time. We diverted to airport ZZZ and eventually made it to ZZZ1. This put our daily estimated block time at 8 hours 59 minutes. During our preflight procedures the captain and I had numerous discussions with crew scheduling; dispatch; and the chief pilot on call. We were discussing the fact that someone had changed the scheduled block time from ZZZ1-ZZZ from 1 hour 10 minutes to 59 minutes. The burn time calculated by dispatch was 44 minutes. This gave us 15 minutes plus the 44 minute burn to taxi out; takeoff; and taxi into the gate in ZZZ in order to stay compliant with the far 117 rule of 9 hours of block time.we questioned how dispatch came up with that number with the amount of weather in the ZZZ area. We were told that as long as we taxied out in 12 minutes and took off we would be legal. We taxied out to the runway. Upon reaching the runway we were at 10 minutes since block out. We took off thinking we were legally at or under the 12 minutes since block out. After departing; we noticed that the ACARS marked our off time at 13 minutes after block out. When we got closer to ZZZ we heard that aircraft just got out of holding due to weather in the ZZZ area. Although I was not on the phone with dispatch; I don't believe that holding was ever mentioned to the captain by the dispatcher. Had it been the burn and therefore our projected block time should have been increased making us illegal to depart. We ended up blocking in at the gate in ZZZ at 9:06 block time for the day.I don't think it is right that dispatch and/or crew scheduling can adjust the projected block times. Originally ZZZ1-ZZZ was scheduled at 1 hour 10 minutes. It was adjusted to a lesser amount (even with lots of weather and come to find out enroute holding in the ZZZ area) to one minute below the 9 hour limit.
