     Sunday is more like Monday than it used to be. Places of business that used to keep daytime "business

hours" are now open late into the night. And on the Internet, the hour of the day and the day of the week

have become irrelevant (不相关的). A half century ago in the United States, most people experienced dividing

lines between days of rest and days of work, school time and summer time. Today the boundaries (界限) are

still present, but they seem not clear.

     The law in almost all states used to require stores to close on Sunday; in most, it no longer does. It used

to keep the schools open in all seasons except summer, in most, it still does. And whether the work week

should strengthen (加强) its legal limits (法律限制), or whether it should become more "practical" is often

discussed. How should we, as a society, arrange our time? Should we go even further in relaxing the

boundaries of time until we live in a world in which every minute is much like every other?

     These are not easy questions even to ask. Part of the difficulty is that we seldom care about the "law of

time" even when we meet it face to face. We know as children that we have to attend school a certain number

of hours, a certain number of days, a certain number of years - but unless we meet the truant officer (督学),

we may well think that we should go to school due to social custom( 习惯) and parents' demand (要求) rather

than to the law. As adults we are used to "extra (额外的) pay for overtime working", but less used to the fact

that "overtime" is a matter of legal definition. When we turn the clock forward to start daylight-saving time,

have we ever thought to ourselves; "Here is the law in action"? As we shall see, there is a lot of law that has

great influence on how to arrange and use time: compulsory education law, overtime law, and daylight-saving

law-as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin

to look for it, we will have no trouble finding a law of time to examine and assess (评价).
