OH3 - Convert from Joda DateTime to ZonedDateTime

I need to update my Jython rules because Joda has been removed from OH3.

How can I achieve this with ZonedDateTime and DateTimeType in OH3?

from org.joda.time import DateTime

events.postUpdate("Awair_LastUpdate", str(DateTime.now()))

Tried different things here, but none of them worked. Mainly because I think I don’t know how I could format the ZonedDateTime to get accepted by the DateTimeType

So why not just create a new DateTimeType? Without arguments it defaults to now.
