LMAO, actually thinking back at the time line for the group it went as follows - 

Night came...Met in tavern, left that night, gnolls attack that same night, orc found that same night, sun rose when they reached the place, maybe were half way through the daylight of that day. After all the fighting and such... we might and this is stretching it, be at evening. So we are less than 24 hours.
