Role of の and meaning in the sentence "その瞬間の自分の手に〇〇がにぎられている"


The complete sentence, although I don't think it is necessary, is the
following:

> その瞬間 **の** 自分の手に、人類すべての運命を決定付けるような、重大なターニングポイントがにぎられているなんていうことは、分かるはずがないんた

So, if the intended role of その瞬間 was to be "in that moment" wouldn't it be
その瞬間に instead of の? Or is it that 瞬間 acts like an adverb or "の adjective" here
and transforms the meaning of the sentence into something like "I was holding
such and such for such a short moment".

I don't really know if my possible interpretations make any sense, so I hope I
can get some help.




The の is normal _of_.

You can use に as well.

  1. その瞬間 **の** 自分の手にXがにぎられている
  2. その瞬間 **に** 自分の手にXがにぎられている

are both fine, literally corresponding to

  1. X is held by my hand **of** that moment.
  2. X is held by my hand **in** that moment.

'My hand' in a particular moment can be called 'my hand of that moment' (in
Japanese, at least).
