Rules and complex time comparisons

Hi @Wolfgang_S,

thanks - that was quick and got me in the right direction, I think.
After a bit more digging, I came up with this:

rule "LimitAussenlichtMorgen"
when
//             s m  h d M dow y
    Time cron "0 0 6 * * * *" 
then
    // before switching on the light, check
    // that the sun has not yet risen
   var day_start = (Sun_rise_StartTime.state as DateTimeType).getZonedDateTime()
   if ( ( now().isBefore(day_start) ) ) {
    Aussenlicht.sendCommand(ON)
   }
end

I guess this should work; will see tomorrow.

Thanks a lot!

Cheers

Marco
