use jode in rules or scripts

[helmut....@ingenieurbuero-mbi.de]

Hi all,

the following is perhaps a noob question. It this is the case, just give me the right hint, and I´m sorry.

I´d like to use a joda-time calculation/API access to get the current time for the UTC timezone, to calculate sunrise and sundown independent from summertime (daytime saving time).
So I have to get the current time in a way like this :

var check = now.withZone(DateTimeZone.UTC)

jode-time API docs state, that UTC timezone is defined as a field, so this should be correct, but designer marks it as error and the rule engine throws errors, too :

Message: Error during the execution of rule Set Sun and Dawn States
java.lang.RuntimeException: The name 'DateTimeZone' cannot be resolved to an item or type.
    at org.openhab.model.script.interpreter.ScriptInterpreter.internalFeatureCallDispatch(ScriptInterpreter.java:67)
    at org.eclipse.xtext.xbase.interpreter.impl.XbaseInterpreter._evaluateAbstractFeatureCall(XbaseInterpreter.java:658)
    at sun.reflect.GeneratedMethodAccessor40.invoke(Unknown Source)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
    at java.lang.reflect.Method.invoke(Method.java:606)
    at org.eclipse.xtext.util.PolymorphicDispatcher.invoke(PolymorphicDispatcher.java:291)

Obvious and understandable, I have to import the required parts of joda-time, but I do not find any suitable jar to include within openhab files, the assumed

import org.joda.time.DateTimeZone

didn´t solve this issue.

So, my question is, how could this be done. I didn´t find any documentation with regard to joda-time together with openhab, just a pull request for updating joda to ver 2.3, so i assume it should be there and also it should be available to scripts; or is there only a subset without timezone support available within openHAB ?

Thanks for your time and your help

cheers,

Flipper

Hi,

You almost have it right. You indeed need the import

import org.joda.time.DateTimeZone

and then you need to use double colons as you are doing a static reference. So your variable definition has to be

var check = now.withZone(DateTimeZone::UTC)

Hope this helps!

Kai
