I’m not sure the elves measure time at this point. I mean, some of them could, and later, someone could say, ‘the Sun has now crossed the sky five hundred times’ and people will be impressed or uninterested or whatever. But at this moment, the passage of time isn’t that interesting. The Sun is up. The Noldor have arrived. The enemy has been dealt a serious blow. Maedhros is missing. Those facts are interesting, but, since no one is sick or dying of age, or food is running out, or furniture needs replacing, the amount of time that has passed or is about to pass is of no consequence. So we really have no reason to indicate how much time has passed at this point, I think.
