It looks like this mod doesn't support other surfaces (that might not have a day/night cycle) so I suspect mods like factorissimo will also crash.
I'd also check if other modded planets work properly (hopefully)
The mod What Time Is It (1.0.2) caused a non-recoverable error.
Please report this error to the mod author.
