用trader界面 下ib单以后（成交也没问题），会触发一个异常，异常信息如下：
Traceback (most recent call last):

ValueError: unconverted data remains: Hongkong看了下这部分代码ib_gateway.py execDetails里，看着是解析时间错误，把execution.time打出来，
def execDetails(self, reqId: int, contract: Contract, execution: Execution) -> None:
"""交易数据更新回报"""
super().execDetails(reqId, contract, execution)
print("-------------------") #我加的
print(execution.time) #我加的
if "/" in execution.time:
timezone = execution.time.split(" ")[-1]
time_str = execution.time.replace(f" {timezone}", "")
tz = ZoneInfo(timezone)
else:
time_str = execution.time
tz = LOCAL_TZ
dt: datetime = datetime.strptime(time_str, "%Y%m%d %H:%M:%S")
dt: datetime = dt.replace(tzinfo=tz)输出是这样的

代码里用"/"来判断是否接了地域信息，实际打出来好像没有"/"，不知道哪里出了问题
