How to do playback mode #5

Open maxott opened 12 years ago

Apart from live updates, we're planning to add a playback mode where we can set the clock back using a 'slider'.

That's not there yet, but something I definitely want to support. It's actually quite easy to do if it's related to a timestamp which is consistent across all data sources. You can do it from the backend where you extend the OML server query with a 'timestamp < X' clause. Another solution would be to do this in the browser. Extending data_source.js to filter on a global 'wall clock' would be quite easy as well (assuming that each schema is having a 'dominant timestamp' synched to a common clock.
