Time travel without freezing

[jvdp]

I'd like to use this library for acceptance tests (ie. running the web app + JS frontend in a browser / phantomjs) that involve time-dependent data, so the clock needs to be set back to a certain date. My app also uses lodash' debounce function, however, which relies on the passage of time. Because I don't really have a good place to put a tick statement the clock shouldn't be 'frozen' at a particular moment but it should advance as normal from the system date specified.

This would like the travel method of Timecop.js (which is deprecated in favor of sinon / lolex.)

I don't see how this could be implemented without async behaviour, which means you just might as well just put tick calls in some endless setInterval or process.nextTick loop yourself.

We can take a timestamp of when time travel starts and then compute the difference to determine the adjust "current" time. Timecop.js does this: https://github.com/jamesarosen/Timecop.js/blob/master/lib/TimeStackItem.js

True, just computing the nowvalue based on the diff is easily done. Such a feature should be quite easily implemented. Must have been to late to think clearly 😄 Care to take a stab at it?

Will see what I can do.

Has this issue stalled?
