Hi I've seen time-based acl in two different formats. For example if I want to define the range from 8am to 5pm I've seen sometimes this format
periodic weekdays 08:00 to 16:59
while elsewhere they are in the format
periodic weekdays 08:00 to 17:00
The reason why you write 16:59 is that the range actually lasts till 16:59:59 so from 17:00 onwards the acl is no more active, while if you write 17:00 it will be active until 17:00:59. However I've seen the second format so many times in so many places.
What is the exact way of writing a time-based acl? or better, what is the way of writing an acl that is considered correct at the lab? I think this is one of the stupid tricks that make you lose points.
