fixed timespec_get() initialization bug on some targets

Browse Source 
not sure why, but msan fires an "unitialized variable" error
when time gets properly initialized by timespec_get().
Maybe in some cases, not all bytes of the structure are initialized ?
Or maybe msan fails to detect the initialization ?

Anyway, pre-initializing the variable before passing it to timespec_get() works.
