我在DolphinDB databse中创建了如下流数据表：
st=streamTable(
array(LONG,0) as id,
array(TIMESTAMP,0) as ts,
array(DATETIME,0) as dt,
array(DOUBLE,0) as value
)
share(st,"demoSt")
我想在python中把当前系统时间写入流表，代码如下：
import dolphindb as ddb import numpy as np import pandas as pd s = ddb.session() c=s.connect("192.168.1.125", 8848, "admin", "123456") s.run("tableInsert{demoSt}", [1,np.datetime64('now',"ms"),np.datetime64('now'),0.01 ])
运行后，我查询得到的数据如下图所示：
这里有2个问题，一个问题是np.datetime64('now',"ms")得到的毫秒数不对，它总是000；另一个问题是np.datetime64('now')得到的是utc时间，不是localtime。请问要得到正确的时间应该怎么实现？
可用datetime模块中的datetime.now()得到当前时间，代码修改如下：
from datetime import datetime import dolphindb as ddb import numpy as np import pandas as pd s = ddb.session() c=s.connect("192.168.1.125", 8848, "admin", "123456") s.run("tableInsert{demoSt}", [1,np.datetime64( datetime.now(),"ms"),np.datetime64(datetime.now()),0.01 ])
