title: SQLite query that calculates if Unix epoch time occurs on today's date
body: <p>I have an integer column that holds a Unix epoch time value. I want to calculate if it falls within today.</p>
  
  <p>For example, let today be the 24th day in the month. The query should return rows that fall on the 24th, but not ones that fall on the 23rd or some time before that.</p>
  
  <p>Thanks for looking.</p>
