Negative timestamps occur by using a Notifier to record CAN messages from multiple channels

Describe the bug

Negative time occurs when recording many channles CAN messages and channel changes

To Reproduce

创建自定义日志记录器

log_writer = can.Logger('test.asc')

def handle_message(msg): print(msg) log_writer.on_message_received(msg)

_can = Can_interface(driver_list=['kvaser', 'vector']) buses = { '1': _can.open_driver(3), '2': _can.open_driver(4), } notifiers = list() for channel, bus in buses.items(): # 注意:先添加过滤器,再添加处理函数 notifier = Notifier(bus, []) notifier.add_listener(handle_message) notifiers.append(notifier)

Expected behavior

I hope to record the CAN messages of different channels in a way that is consistent with the actual received message, and can be kept consistent with 'canoe'

Additional context

OS and version:win10 Python version:python 3.9.13 python-can version:4.2.0 python-can interface/s (if applicable): vector
