There are a few specialized debuggers which allow time-travel to one degree
or another.

However, to do this they need to save lots of information every time the
program 'steps' whether you are stepping through the program with the
debugger or just letting it run.  I'm not sure I'd want to endure the
overhead until I really needed it.

Here's a link to someone at Cisco who extended Eclipse to allow such
temporal debugging using a complete system simulation for an embedded
system:

And here's a google video of Bil Lewis demonstrating his "Omniscient
Debugger" for Java.
