Been answered numorus times befor, but here it is onece again:
In the sourcecode there is a file called buildtime.h
If you open it with notepad etc you will see a date.
and yes, you guessed it, by default it says 25 july.
If you change it to the 45 of december 2054 that is what the buildtime will show up as in xbmp

EDIT.
Here is the content of the file...
#ifndef BUILD_TIME_H
#define BUILD_TIME_H
! #define BUILD_TIME L"Build:27 Oct. 2003 17:30"
#endif
