It would mean that, inthe north of Scotland, it did not get light until 10am in winter, and the Scots have therefore decided that it is a Sassenach plot to ensure that the Highlander is kept inthedark.
There is too much trolling around inthedark, and some garbled and repetitive plot turns inthe film, but, when the action breaks out across that slate-colored plain, Scott uses 3-D well, giving the movement persuasive depth.
