Hi Andreas,

thanks for your comment. The reason why I sent the patch is that there 
is a bug/feature request for similar functionality in coreutils' "date" 
program and the maintainers of coreutils/gnulib do not want to diverge 
from the glibc interface. Even though the replacing you mentioned does 
indeed work, built-in version would be imo better (for example when 
using other shell than bash), especially when all of the needed 
functionality was already implemented.

Jakub
