Because you can generate some suitable error message if the clock is
missing due to some misconfiguration or other error. Always checking
return values is a bit annoying, but it's usually the right thing to do.

You could check the return value for every call, and stop using it if it
fails (which clearly will be the first call, in any normal situation).
