I think that is not a good idea. First of all, I can't define these consts everywhere,so I have to create a new package(eg:mytime) to define them. And then, client package may use like this: import( "time" ".../mytime" ) dur2WeeksAnd7Hours := mytime.Week*2+time.Hour*7 I think this code may make the clients crazy...
