# 同步网络时间
板卡自带了 wifi 可以通过导入相关库进行网络编程

## 连接网路
- 示例代码
        ```python
        from machine import Pin, Timer
        import time
        import network

WIFI_SSID = "your-ssid"
        WIFI_PASSWORD = "your-password"

led = Pin("LED", Pin.OUT)
        wlan = network.WLAN(network.STA_IF) # Connect to WiFi
        wlan.active(True)

access_points = wlan.scan()
        for AP in access_points:
                print(AP)

wlan.connect(WIFI_SSID, WIFI_PASSWORD)
        while not wlan.isconnected() and wlan.status() >= 0:
                print("Waiting to connect:")
                led.toggle()
                time.sleep(0.25)
        print("Connected to WiFi!")
        print(wlan.ifconfig())
        ```

- 运行效果
        ```python
        >OK
        MPY: soft reboot
        raw REPL; CTRL-B to exit
        >OK

(b'shanghai2014', b'\xa8WN\x80\x81r', 3, -28, 7, 6)
        (b'TP-LINK_501', b'`:|\x96\xf5\x9d', 3, -87, 7, 1)
        (b'ChinaNet-ApM5', b'\x88]\xfbf\x0bo', 5, -91, 7, 2)
        (b'ZTE-201', b'x\x96\x82\xa0\xba"', 11, -81, 7, 1)
        (b'CMCC-301', b'\xb8\x805\x1f\xd6d', 11, -96, 7, 1)
        (b'ChinaNet-DD9q', b'0\xd3\x86\xe7B\x03', 12, -86, 7, 2)
        Connected to WiFi!
        ('192.168.0.3', '255.255.255.0', '192.168.0.1', '211.136.150.66')
        ```

## 获取网络时间
- 示例代码
        ```python
        from machine import Pin, Timer, RTC
        import time
        import network
        import ntptime

WIFI_SSID = "your-ssid"
        WIFI_PASSWORD = "your-password"
        UTC_OFFSET = 8 * 60 * 60

led = Pin("LED", Pin.OUT)
        rtc = RTC()

# Connect to WiFi
        wlan = network.WLAN(network.STA_IF)
        wlan.active(True)

access_points = wlan.scan()
        for AP in access_points:
                print(AP)

wlan.connect(WIFI_SSID, WIFI_PASSWORD)
        while not wlan.isconnected() and wlan.status() >= 0:
                print("Waiting to connect:")
                led.toggle()
                time.sleep(0.25)
        print("Connected to WiFi!")
        print(wlan.ifconfig())

# Get the current network time and set the system clock
        print("Local time before synchronization：%s" % str(time.localtime()))
        ntptime.timeout = 3
        ntptime.settime()
        utctime = ntptime.time() + UTC_OFFSET
        print("Local time after synchronization：%s" % str(time.localtime(utctime)))
        ```

- 运行结果
        ```python
        Connected to WiFi!
        ('192.168.0.3', '255.255.255.0', '192.168.0.1', '211.136.150.66')
        Local time before synchronization：(2023, 6, 7, 14, 19, 21, 2, 158)
        Local time after synchronization：(2023, 6, 7, 22, 19, 21, 2, 158)
        ```

可以看到转换之后localtime 已经换算成了东八区的时间

wifi 导入相关库进行网络编程，时间同步，是这样整的
