Yes, I believe so.  As others have pointed out, current copyright law (I believe in most countries, as part of the current copyright treaty arrangements) is that copyright is automatic.  That replaces an earlier US rule that copyright only applies if explicitly claimed.  This is why ADO added explicit "this is in the public domain"notices in the TZ files.

Given the mission of IERS, it would seem that this should not be an issue.  It's pretty likely that the absence of a statement in the files is an oversight, perhaps caused by an assumption that absence of a stated restriction means there isn't a restriction.  (But in fact, absence of statement means no permission -- it doesn't mean no restriction...)
