The flow of time it's self is not entirely straight, it can be warped, twisted and spun like space it's self, so while at times it is entirely possible for time to go backwards or skew, it is for all practical purposes fine to think of it as being straight.
Entropy still either increases or stays constant over time in a closed system.
