So this seems to be undoing commit 80fa614e2fbc ("selftests: timers: Remove local NSEC_PER_SEC and USEC_PER_SEC defines")
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
