推荐答案

如果你不能相信CMOS电池，那么你需要从互联网上获取时间。您可以使用许多互联网时间服务器：Google可以帮助您，只需查找NIST或NTP服务器。



设置系统时钟虽然是特权操作 - 这意味着您需要管理员权限才能执行此操作。代码很简单： http://msdn.microsoft.com/en- us / library / ms172517（v = vs.90）.aspx [ ^ ] - 但它可能更像是你想要的PITA。



我？我要更换电池 - 它们并不昂贵，旧的漏电池会严重损坏PCB！

IF you can't trust the CMOS battery, then you need to get the time from the internet. There are a number of internet time servers which you can use: Google can help you, just look for NIST or NTP servers.

Setting the system clock though is a privileged operation - which means you need admin permissions to do it. The code is simple: http://msdn.microsoft.com/en-us/library/ms172517(v=vs.90).aspx[^] - but it may be more of a PITA that you want.

Me? I'd change the battery - they aren't expensive and old leaky batteries can do serious damage to the PCB!
