How to correctly parse Time field in GenericCSVData?

pan harry

Here's my csv data looks like:

2022/11/15,0905,1411,1418,1407,1417,33899,749118,0
2022/11/15,0910,1417,1419,1415,1418,23688,753590,0
2022/11/15,0915,1418,1419,1410,1410,20393,752823,0

the 2nd field indicates the time , I try to use GenericCSVData to parse the date and time

    data = btfeeds.GenericCSVData(
        headers=False,
        dataname=file,
        fromdate=datetime.datetime(2000, 11, 15),
        todate=datetime.datetime(2022, 11, 16),
        nullvalue=0.0,
        dtformat=('%Y/%m/%d'),
        tmformat=('%H%M'),
        datetime=0,
        time=1,
        open=2,
        high=3,
        low=4,
        close=5,
        volume=6,
        openinterest=7
    )

but when I try to use

self.datas[0].datetime.time(0)

to access time field in next() method, it always gives me 23:59:59.999989
Is there anything I understand incorrectly?
Any comments would be appreciated

Thanks

@pan-harry Have to tried to specify the timeframe of your csv data ?
Like adding :
timeframe=bt.TimeFrame.Minutes, compression=5,
