How can I find the current date in intel x86 Assembly?

Question

I need to find the find the current date in binary for Intel x86 Assembly on Windows. I'm allowed to use Windows procedures.

Answer 1

If you're allowed to use Win32 functions, then the answer to this would be the same as the answer to "How can I find the current date in C on Windows?" For this, look up the GetSystemTime and SystemTimeToFileTime functions (hey neat, there's even a GetSystemTimeAsFileTime function now! (since Windows 2000)).

Answer 2

Not sure if this is technically "Windows" (and indeed only works in Windows' emulated DOS environment aka NTVDM, as confirmed by Greg Hewgill), but you could use INT $21, with $2A in AH, as this DOS function will return the date. See this link for more info
