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

Question

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 B         


        

Answer 1

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
