Incomplete, but this could get you started:

Research the ability to run a script or executable from within  
Windows gmake. Copy stdout into a Make variable something like this:

CFLAGS += -DThe_Date_Is=`date`

Create a project file named something like makedate.c and tweak the  
Make rules so that makedate.c must be built for the situations you  
wish the date to be updated.

makedate.c would look something like:

const char My_Build_Date[] = "The_Date_Is";

gcc already has a bluzillion predefined environment variables. I  
wouldn't be surprised that one contains date and time stamp, lets check:

% touch foo.h ; avr-cpp -dM foo.h

Nope, didn't see a timestamp.
