 .. admonition:: what is NTP
 
     Network Time Protocol (NTP) is a protocol used to synchronize the time of the computer. It can synchronize the computer to its server or clock source (such as quartz clock, GPS, etc.). It can provide highly precise time calibration.
+Note: There's currently no timezone support in MicroPython, and the RTC is set in UTC time.

 Method

-.. method:: settime(timezone=8,server = 'ntp.ntsc.ac.cn')

-Synchronize local time
-
-    - ``timezone`` - Time zone time difference, the default is East Eight District, compensation 8 hours
-    - ``server``  -  You can specify the time server yourself, server is a string type. The default time server is "ntp.ntsc.ac.cn" .
