Hi,
As jkandasa said, you should probably download the last SNAPSHOT version again. Your error message seems to be because you don't have the SNAPSHOT with his modification.
As for the step-by-step i can try to explain the way i did it:

First, i'm using a Raspberry Pi Zero for the controller with an up-to-date Raspbian distro. I have the last 0.0.3.Final-SNAPSHOT of MyController.org(at least the one from 24 days ago with jkandasa's modification). I'm using the 2.0.0 version of MySensors (soon to be updated to the last version). On MyControler.org i created 2 UID tags (sunrize and sunset) which point to 2 dummy sensors (child of a MySensors node). Then i have the java script which send the sunrize and sunset value to this UID tags: var myImports = new JavaImporter(java.io, java.lang, java.util); with(myImports) { //Get Sunrise/Sunset details var locSettings = mcApi.utils().getServerLocationSettings(); //Get sensor variables for sunrise and sunset var sensorSunRise = mcApi.uidTag().getByUid("sunrize").getSensorVariable(); var sensorSunSet = mcApi.uidTag().getByUid("sunset").getSensorVariable(); //Update timezone offset values (by default gives GMT timestamp values) //sensorSunRise.value = locSettings.sunriseTime + locSettings.timezoneOffset; //sensorSunSet.value = locSettings.sunsetTime + locSettings.timezoneOffset; var dtr = new Date(locSettings.sunriseTime); sensorSunRise.value = dtr.getHours() + ':' + dtr.getMinutes(); var dts = new Date(locSettings.sunsetTime); sensorSunSet.value = dts.getHours() + ':' + dts.getMinutes(); //Send/Update thise sensorvariable with updated value mcApi.sensor().sendPayload(sensorSunRise); mcApi.sensor().sendPayload(sensorSunSet); } On MyControler.org i created an Operation to execute the java script and a Timer to start the Operation before Sunrize every day.

For your java script you just need to add an if statement comparing the sunrize and sunset values with the current time, and you should be good.
