Let relativeTimeFormat be this value.

that should be phrased as:

Let relativeTimeFormat be the this value.

The phrase "the this value" means the value of the binding of reserved word this within a function activation. If the phase isn't qualified with a specific function, it is referring to the the this value of the currently function activation. That standard three word phrasing is intended to be consistency used through out the spec. to avoid confusion cause by the inclusion of alternative phrasings that may or may not mean the same thing. If you search for the phrase "the this value" within ECMA-262 you will see how the this value is set and accessed.

The phrase "the this value" is used throughout the JS spec to refer to the receiver. Presumably, this wording is intended to be more clear than simply "this" but I don't really know the background. Maybe @allenwb @anba @jmdyck @bterlson could know more.

Probably 'value' is a confusing choice of parameter name. Would it clarify things for you if the name changed? Separately, I think we need to make a spec concepts/ecmarkup glossary, since it can be a bit hard to get through the notational conventions part of the spec that defines these things.

The phrase "the this value" goes back to ECMA-262 1st edition (so way before my time).

Separately, I think we need to make a spec concepts/ecmarkup glossary, since it can be a bit hard to get through the notational conventions part of the spec that defines these things.

You're thinking it would be easier to get through the glossary?

We also have something like ToObject(*this* value) in 262 and 402. Maybe those can be fixed by splitting them into two steps to avoid confusion.

Agree with @allenwb on this one. The added the helps clarity a lot.
