下载的数据：时间09:00:00.000000000有9个0

然而tafunc.time_to_s_timestamp和tafunc.time_to_str都是6个0

有点不一致啊

kzhui125 commented 5 years ago 
def time_to_s_timestamp(t):
    return 1e9 * tafunc.time_to_s_timestamp(t[:-3])

klines = pd.read_csv('rb_1M.csv')
klines['datetime'] = klines['datetime'].apply(time_to_s_timestamp)

不过封装下就好了
