Sounds like another philosophical question but no, you can relax. This is another developmental (yes almost mental) posting.<\/p>\n

Say you need to create a piece of functionality that must only operate within a predefined time period of a day – call it a ‘service window’. It could be that you may even need several of these ‘windows’ per day – i.e. if there is a pause period inside the day and work must be processed before (up until) and after the pause.<\/p>\n

For this kind of functionality I created a ‘ServiceWindows’ class. It basically host a list of ‘from’ and ‘to’ times plus methods that makes it possible to find out if a specified time is somewhere ‘inside’ or ‘outside’ any ‘service window’. Additionally the class can be ‘populated’ from an xml config string so it can be used in applications that operates from xml config files.<\/p>\n

So without much further chit-chatting here is the guts of the class (not for sensitive readers \ud83d\ude09<\/p>\n
