Error launching simulation: Error: EINVAL: invalid argument, readlink '/etc/localtime'

Hi team,

When I run this config /examples/urbo-simulation-environment.json raise this error:

Do you know what could be happening? It has started to happen suddenly.

Thanks!

Uhmm... Never got that error, sorry :( Since it is related to the native code of the "time" package, have you tried to get the latest updates from master and running "npm update" followed by "npm rebuild" just to force the rebuilding of the native code and check how it goes then? :)

Thanks @gtorodelvalle ! I pulled latest updates from master branch and now it's running. I'm going to monitor this simulation and if I see something strange I say you. I close the issue.

@gtorodelvalle I reopened this issue because simulation does not work well. We have a dockerized simulator which it is rebooted in each simulation (it sends data to Context Broker but after this it crash with the same time error).
