The intended meaning of "the hour" in the hadith: (Whoever comes in the first hour...)

Question:
This questioner is Abdullah from al-Ahsa... al-Mubarraz. He says in the question: What is meant by the first, second, third, fourth, and fifth hours of Friday? Are they the commonly understood hour, or a relative time? And when does the first hour begin?

Answer:
The most likely view—and Allah knows best—is that it begins after the sun has risen the height of a spear; because it is prescribed for the believer to sit in his place of worship, remembering Allah and making supplication until it rises. So the most likely view—and Allah knows best—is that it enters when the sun rises. The day is divided into six hours, from when he leaves his mosque, or his home, until the preacher enters. These six hours vary according to the length or shortness of the day. In the first hour, it is as if one offered a camel; in the second, as if one offered a cow; in the third, as if one offered a horned ram; in the fourth, as if one offered a chicken; and in the fifth, as if one offered an egg. The time between the rising of the sun and its setting is twelve hours, divided according to the length or shortness of the day. Yes.
