    commit 65c6434b59efe33c3484556c35e9c737ef99400d

        Match automatically updated times on models
        
        On a model with multiple fields with auto_now_add or auto_now, the time
        may differ on each save. Instead, we record the time when a transaction
        starts and use this time whenever a value is required.
