How can I set item data as DateTimeType - 10 minutes?
I’m using now the item.postUpdate(new DateTimeType) but I need to set the time -10 mintues (I’m using it to know when I’m living home - no ping for 10 minutes, I want to update the item to -10 minutes)

But it is not DateTimeType and it is not recommended to use it as far as I remember, am I wrong?

Oh, sorry. I didn’t note that the types are differen. The following article shows some possibilities to convert Joda DateTime to DateTimeType. Maybe it helps:

Thank look like it is not updated.
The constructor DateTimeType(Calendar) is deprecated
