        {
            var secondsSinceEpoch = (long)Math.Floor((BsonUtils.ToUniversalTime(timestamp) - BsonConstants.UnixEpoch).TotalSeconds);

            if (secondsSinceEpoch < int.MinValue || secondsSinceEpoch > int.MaxValue)
            {
                throw new ArgumentOutOfRangeException("timestamp");
            }
            return((int)secondsSinceEpoch);
        }
