1) Give a description of the problem
Need a piston to activate at sunset or a specific time, whichever is later.
2) What is the expected behavior?
Activate at sunset or time, whichever is later. In other words if I want it to activate at say at 5 pm and sunset is 4:45 pm then activate at 5 pm. Conversely if sunset is 5:30 pm then activate at 5:30 pm. And also with a before offset to sunset to make things more interesting.
3) What is happening/not happening?
Nothing yet as I have been unable to figure it out.
Thanx in advance.
