Omniscient Debugging

„Omniscient Debugging is the idea of collecting "time stamps" at each "point of interest" (setting a value, making a method call, throwing/catching an exception) in a program and then allowing the programmer to use those time stamps to explore the history of that program run. The ODB is an implementation of this idea written in Java. It inserts code into the .class files to collect these stamps and when the program runs, time stamps are recorded.“
