Bloody rediculous having a time zone for school zone limits. Should be one speed no matter what time of the day it is. having school age kids myself I would like to see them 20kmh all day everyday. School zones arent that big really so a little inconvenience for a few people is a small price to pay to know there is a little less chance a kid is going to get skittled.... If people speed in school zones they deserve what ever they get
