Postpone an item in the queue

Good afternoon community!
I need to postpone an item in the queue, but not using the activity calendar but an expression, but what type of expression would I use to define the current date (execution date) and the time until 3 PM?

Click on plus on right and open advanced editor and then You can use DateTime.ParseExact(DateTime.Now.ToString("MM/dd/yyyy") + " 15:00:00","MM/dd/yyyy HH:mm:ss",System.Globalization.cultureInfo.InvariantCulture)

Cheers
