Fix nonportable printf format
%L is a glibc extension, so fix it to standard %ll. Because it didn't work properly with libraries other than glibc. Hertz is unsigned so modified to %llu.
from: man 3 printf
As a nonstandard extension, the GNU implementations treats ll and L as synonyms, so that one can, for example, write llg (as a synonym for the standards-
compliant Lg) and Ld (as a synonym for the standards compliant lld). Such usage is nonportable.
