Nanosecond date resolution

By default ext3 stores file with 1 second date resolution but I have  
read it is possible to enable big inode and that will improve  
resolution to 1 nanosecond.

How can I enable the 1-nanosecond date resolution? I've found some  
mails by Alex Tomas, Andi Kleen and Andreas Gruenbacher to the linux  
filesystems mailing list but no clear way to enable this feature. Will  
it harm performance? (I do know it consumes more space)

Thank you
