时区，Python和ZeroSeg

Question

我买了ZeroSeg。它是一个与Raspberry Pi连接的8字符7段显示器。它使用Python，我无法弄清楚如何更改时区。有一段时间出现的代码：

import time
from datetime import datetime

now = datetime.now()
if mode == 1:
        hour = now.hour
        minute = now.minute
        second = now.second
        dot = second % 2 == 0
        # Set hours
        device.letter(1, 8, int(hour / 10))     # Tens
        device.letter(1, 7, hour % 10)     # Ones
        device.letter(1, 6, " ", 1)
        # Set minutes
        device.letter(1, 5, int(minute / 10))   # Tens
        device.letter(1, 4, minute % 10)        # Ones
        device.letter(1, 3, " ", 1)
        # Set seconds
        device.letter(1, 2, int(second / 10))   # Tens
        device.letter(1, 1, second % 10)        # Ones
