Thanks John, I somehow missed 80fa614e2fbc and was wondering how
this had got in.

> Would it make more sense to fix the NSEC_PER_SEC definition in time64.h to a LL?
I was just thinking the same this morning but wasn't sure if this would cause
issues anywhere else.

I'll send a patch to change NSEC_PER_SEC in time64.h as its a lot cleaner
that way.

Thanks
Terry
