Am new with json code and openremote software

i want to covert unix to datetime any solution can i try ?

any one can explane me about json code it will be helpfull thank

You could try setting the value type of the attribute to timestamp and it should then display in UI as a date time control.

Other option would be to use a groovy rule to update another string attribute with a formatted date time.

i already try it but not thing change
