Well if you already know how to connect and retrieve data from the SQL server, then all you need is to access the current time/data from the computer and compare it to the one from the server. Some simple maths will do the rest. Here is the date/time class reference for C# https://msdn.microsoft.com/en-us/library/system.datetime(v=vs.110).aspx
