String to datetime?

Hi,
I receive a string from Tasker (Android) with the seconds till the alarm starts…

How can I show the alarm time ?

I tried something like this:

var int zeit = (heiz_wecker_joerg_timer.state as DecimalType).intValue
val alarmDT = new DateTime(now.plusSeconds(zeit))
heiz_wecker_joerg.sendCommand(alarmDT)

But the Designer gives me an error:

Type mismatch: cannot convert from DateTime to String

How can I solve this ?
Regards
Jörg

I found the answer by myself :grin:

heiz_wecker_joerg.sendCommand(alarmDT.toString)
