Time-travel debugging and omniscient debugging are different. For example, https://rr-project.org https://rr-project.org is a time-travel debugger --- it can simulate executing backwards through time --- but it is not an omnisicient debugger because it doesn't provide fast access to all program states. https://pernos.co/about https://pernos.co/about is an omniscient debugger built on top of rr: it provides fast access to all program states and visualizations built on top of that.
