This question came from our site for professional and enthusiast programmers.

IIRC, Windows queries the machine CMOS clock to get the datetime at installation/repair time.

@pvaju896: IIRC = "If I Recall Correctly" And how would you like to retrieve said time? C#?, VB.NET, other? If you're installing something on Windows, just access the system clock (DateTime.Now in C#). – AllenG Aug 11 '10 at 16:10
Not DateTime.Now works from System time.. Other one counter- clock is running with BIOS.. It is actully retreiving value from BIOS(Other CHIp).. How can we retreive that couter value..?? – pvaju896 Aug 11 '10 at 16:56
