[Question] Emulate unsynchronized clocks

[ghost]

Hi @alexei-led,

This is a rather question or may be a feature request, since I cannot see unsynchronized clocks emulation in documentation, so, my question is that is there a way to emulate clock skew for selective or a subset of containers, similar to other commands like delay, pause and so on, or could it be added?

TIA

@lazerion any idea how to implement this?

@alexei-led currently, none, but I will research, and share my findings. I hope it was not a rhetorical question :)

Jepsen does it by running a small c program - https://github.com/jepsen-io/jepsen/blob/master/jepsen/resources/bump-time.c
