After dark

You have not brought him, Eumaios. What does the wanderer mean by this? Does he fear someone so very much? Or is he otherwise ashamed in this house? It is a bad thing for a beggar to feel shame.

At 16:15 Eumaios is getting back to Penelope.

Odyssey Book X line Y-Z Barry B Powell

The sun disappearing behind Mount Ithakos at Ithaca Harbour at 16:45

But Odysseus says, 'No.'

... I am afraid of this crowd of hostile suitors, whose insolence and power reaches the iron sky. Just now, when I was going through the hall doing nothing bad, this men struck me and hurt me. But Telemachos did nothing to ward off the blow, nor did anyone else. For this reason, ask Penelope to wait in the halls until the sun goes down, although she is eager.

At 16:20 Eumaios went to Telemachos and said:

He speaks right, what any other man would think to avoid the insolence of haughty men. But he asks that you wait until the sun goes down, and for yourself too it is much better, my lady, to speak alone with the stranger.

Telemachos answers:

My friend,
I am off to look after the pigs
and other things there, your livelihood and mine. You take care of things here.

And Eumaios answered:

You go off, once you've had your evenig meal. In the morning come back, and bring the beautiful sacrificial victims.

Okay, things are set for after dark and Eumaios will return tomorrow to bring sacreficial swine.
There is going to be a feast tomorrow.
It is now about 16:25 and Eumaios takes his meal.
But there is not much time left. In order to get back to his pig farm Eumaios has to leave at 16:45.
Compleet darkness sets in at 18:00 hours.
It is a 1 hour 15 minute walk to the pig farm and there were no streetlights over Hermes Hill. Not even to date.
