How to format the persistence previousState().timestamp?

[StefanH (Stefan Haupt)]

Hi all,

I cannot see the forrest for the trees. Have searched the forum up and down and saw plenty of posts but I wasn’t able to fix my issue :-/

Here is an extract from my rule:

logInfo("Test", TestSwitch.state.toString)
logInfo("Test", TestSwitch.previousState(true).state.toString)
logInfo("Test", TestSwitch.previousState(true).timestamp.toString)
logInfo("Test", TestSwitch.previousState(true).timestamp.time.toString)

Here the result:

2018-10-22 14:27:26.762 [INFO ] [.eclipse.smarthome.model.script.Test] - OFF
2018-10-22 14:27:26.794 [INFO ] [.eclipse.smarthome.model.script.Test] - ON
2018-10-22 14:27:26.818 [INFO ] [.eclipse.smarthome.model.script.Test] - 2018-10-22 14:25:17.0
2018-10-22 14:27:26.842 [INFO ] [.eclipse.smarthome.model.script.Test] - 1540211117000

How can I format the date value to something like dd.mm.yyyy?

best regards

Stefan

See:

DateTime Conversion (openHAB 2.x)

Because openHAB 3.x rules now use Java Time API instead of Jodatime, there is a new DateTime Conversion thread for openHAB 3.x. Overview In openHab 2.x there are different ways to handle Date/Time values. DateTimeType A DateTime Item carries a DateTimeType. Joda DateTime By default openHAB 2.x-Rules use a Joda DateTime class to represent time, most notably now. Epoch The lowest common denominator when working with time is to get at the epoc value. Epoc is the number of milliseconds …

In particular:

val String MyDateTimeString = MyDateTimeType_item.state.format("%1$td.%1$tm.%1$ty %1$tH:%1$tM"))
