+// C++ iostream operators for logging base::Time, base::TimeDelta and
+// base::TimeTicks objects. For use with DCHECK_EQ(), DCHECK_LE(), etc.  This
+// file is separated from time.h to avoid the iostream dependency, and also
+// because these operators should only be used for logging.
+//
+// Never use these methods to format user-visible strings. See
+// "base/i18n/time_formatting.h" instead.

Optional:  I think it's more common to put file-level comments below the
includes.  People are trained to ignore comments at the start of file - I know
that I'd probably never see this.  Same goes for time_logging.cc.

True. I merged the functionality into time.h anyway.
