Q: How do I get the date/time for this time tomorrow?
A: sleep 86400; print scalar localtime;

Did you see Ilya Zakharevich's response to that? Here it is:

This implementation is very pessimal speed-wise. Here is an important optimization:

        sub tomorrow_date {
          sleep 86_400;
          return localtime();
          sleep -86_400;
        }
