Golden Horns

Telemachos prefers to go by land and spends the night at Nestor's palace. The following morning, before Telemachos and Nestor's son Peistratos set off from Pylos, Nestor makes the following request:

Cow with golden horns, museum Heraklion

Someone needs to go to the field and quickly get a cow, and have the cow herder bring her here right now. Let someone too, go to the black ship of great-hearted Telemachos and bring all his companions, leaving only two. And have someone order Laerkes the goldsmith to come so that he might gild the cow's horns with gold.

We already know it takes about half an hour to walk to the shore, so it'd take at least an hour to accomplish the tasks of bringing the companions, the cow and the goldsmith to the palace. After the goldsmith finishes his work the cow is ritually slaughtered and the flesh tasted. The ceremony takes quite a while, so it must have been several hours after sunrise. Let's say Telemachos and Peistratos leave Nestor's palace around 10 am?

Since Nestor can't provide any information about the wherabouts of Odysseus. Nestor urges Telemachos to go to Sparta...

But I encourage and urges you to go to Menelaos.

...and offers Telemachos the use of his services.

But go now with your ship and your companions, or if you wish to go by land, there is a charriot and horses here, and my sons are here to serve you and be your guides to shinning Lacedaemon, where light-haired Menelaos lives. He will not lie to you. He's a wise and just man.

All day long the horses shook the yoke they had around their necks. The sun went down and all the ways were covered in shadows.

Sunset is at 17:05 and by 17:30 it would've been completely dark, so they travel for about seven and a half hours. Where did they go?
