You can use the __DATE__ predefined preprocessing symbol. To make the source 
file containing it to be always recompiled, use the 'always' rule.

// build_date.cpp
const char * const build_date = __DATE__;

// jamfile
obj build_date : build_date.cpp ;
always build_date ;
exe my_exe : main.cpp build_date ;
