What does it mean that G-d judges people on Rosh Hashanah, if G-d is 'outside of time'?
It's one thing to say that G-d performs an action (e.g. sends the Maan, talks to a prophet) that has a particular time of occurrence as observed in our physical world. But the act of judging itself is not an action observable in the world (though the results of judgement are), but more something that's occurring in the spiritual realms, so how can it have a specific timestamp and be "happening on" Rosh Hashanah?
Could it be said that "G-d judges on Rosh Hashanah" is also referring to something that has a timestamp in this world - such as referring to the notion that the judgement depends on (i.e. is a function of) the state of the person (their merits, etc.) as of the time of Rosh Hashanah (+Ten days of Teshuva)?
