I'm just summarizing the comment that goes with the definition of the 
time_after etc functions:

include/linux/jiffies.h:88
/*
 *      These inlines deal with timer wrapping correctly. You are 
 *      strongly encouraged to use them
 *      1. Because people otherwise forget
 *      2. Because if the timer wrap changes in future you won't have to
 *         alter your driver code.
