主题：history_bars 的时间戳问题

    datetime = history_bars(context.s1, 10, 'self', 'datetime',True)
    print(datetime)

   print 语句运行后  显示的时间是下面的样子

0101:07:59 > [2.02002212e+13 2.02002212e+13 2.02002212e+13 2.02002212e+13
            2.02002212e+13 2.02002212e+13 2.02002212e+13 2.02002212e+13
            2.02002241e+13 2.02002241e+13]
01:08:02 > [2.02002212e+13 2.02002212e+13 2.02002212e+13 2.02002212e+13
            2.02002212e+13 2.02002212e+13 2.02002212e+13 2.02002212e+13
            2.02002241e+13 2.02002241e+13]
01:08:05 > [2.02002212e+13 2.02002212e+13 2.02002212e+13 2.02002212e+13

    a = list(datetime)
    print(a)

把他转成list就能看了，如果你要细分时间这是一个float类型的数字，自己尝试下做做处理
