I am fine with a time change, but I think it really depends on the position of those traveling in Amandur's group. They have a dozen orcs to contend with yet.
As for my group of Naiore, Barrold, & Benia, I am ready to advance the time frame at any time. My plan was for them to start walking again before sunrise and reach the far side of the mountains by sometime the following evening. ?? After that Barrold needs to see about finding a horse for Naiore. When that is done, he will make off toward the Dale with Benia.
