Uneasy question

"Finally done," Layn muttered, wiping his forehead clean from all the sweat. Even though he was no stranger to hard work, ever since he escaped from his original time, there was hardly any time when he had to put as much effort as he did today. 

"Now, I should still have some time before the meeting," he said softly, taking a quick glance at the position of the sun.

Given how there was no clock or anything else that could allow one to measure the time, Layn had no other choice but to use this most primitive and always accessible method. Obviously, that wasn't the case for him personally, but for everyone in the camp as well. As such, until some kind of clock would be mounted in the camp, there was only one moment of the day that could be set as the meeting time. 

The sunset. 

'I still should have about an hour,' Layn thought, loosely judging the speed of the sun and the distance it has yet to travel before hiding behind the horizon line.
