本文为大家介绍了python脚本设置系统时间的方法，一共有两种，其一是调用socket直接发送udp包到国家授时中心，其二是调用ntplib包。我在本地电脑ping 国家授时中心地址cn.pool.ntp.org有时出现丢包，然而，二者都没有检查udp是否丢包的机制，方法一在udp丢包后一直处于阻塞状态无法退出，方法二虽然会提示超时，但是不再做其它尝试，比如重新发包，或者向同一个域名的不同IP地址发包。于是，尝试在方法一的代码基础上，增加了超时机制，并且尝试向同一个域名的不同IP地址发包。
具体修改后的完整代码如下：
#-*- coding:utf-8 -*-import socketimport structimport timeimport win32apiimport osimport redef getTime(TimeServerAddresses): TIME_1970 = 2208988800L client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) client.settimeout(3) data = '/x1b' + 47 * '/0' #TimeServer_ip=socket.gethostbyname('cn.pool.ntp.org') #TimeServer_ip='202.118.1.130' Port=123 for address in TimeServerAddresses: success=False count=0 while not success and count<3: print address,count try: client.sendto(data, (address, Port)) data, address = client.recvfrom(1024) success=True except socket.timeout: print 'Request timed out!' count=count+1 if success==True:a break data_result = struct.unpack('!12I', data)[10] data_result -= TIME_1970 return data_resultdef setSystemTime(now_time): tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday, tm_yday, tm_isdst = time.gmtime(now_time) win32api.SetSystemTime(tm_year, tm_mon, tm_wday, tm_mday, tm_hour, tm_min, tm_sec, 0) print "Set System OK!"def getServerIP(): res1=os.popen('nslookup cn.pool.ntp.org') result1=res1.read() addresses=result1.split('/n/n')[1].split('/n')[1][12:].split(',') return addresses #for address in addresses: # res=os.popen('ping -n 2 '+address) # result=res.read() # received_num=int(re.findall('Received = [0-9]',result)[0].split('=')[1]) # if received_num > 1: # break #TimeServer=addressif __name__ == '__main__': addresses=getServerIP() now_time=getTime(addresses) setSystemTime(now_time) print "%d-%d-%d %d:%d:%d" % time.localtime(now_time)[:6] 以上就是本文的全部内容，希望对大家的学习有所帮助。
