推荐答案

没有互联网时间"之类的东西.您可以从SNTP服务器获取当前时间.有一篇CodeProject文章提供了SNTP客户端类:

C#中的SNTP客户端 [

There''s no such thing as "internet time". You can get the current time from a SNTP server. There''s a CodeProject article that provides a SNTP client class:

SNTP Client in C#[^]

Once you retrieve the time from the desired SNTP server, you can compare that datetime to the datetime retrieved from your SQL server box.
