Print Date and Time In Visual Studio C++ build?

How would I print the date and time for the purposes of the build. Ie: When the console for my application starts up I want to do this:

Binary Build date: 03/03/2009 @ 10:00AM

I think this would be a super useful function for all applications to have behind the scenes for programmers, especially in a team environment.

Is there a simple way to do this using Visual Studio 2008 in C++. Thanks.

Solution

  • Use preprocessor's __DATE__ and __TIME__.

    printf("Binary build date: %s @ %s\n", __DATE__, __TIME__);

    For making sure that cpp file that contains this code is really compiled, I use touch-utility for file as a pre-build step: touch file.cpp

    Touch.bat:

    @copy nul: /b +%1 tmp.$$$
@move tmp.$$$ %1
