Hi,

Please verify the output of the kernel during bootup. Also accessible 
via "dmesg" after login. Make sure to have some sort of message, which 
confirms to activate a real time clock. Setting up a real time clock 
module is an issue of the kernel. Not buildroot itself.
 >dmesg|grep -i clock
or
 >dmesg|grep -i rtc

Regards,
Marcus
