title: Using unix date in OS X (10.6) bash is causing "illegal time format" error
body: <p>I'm unable to use date (under OS X 10.6, using bash) without getting the following "illegal time format" error:</p>
  
  <pre><code>$ date "+DATE: %Y-%m-%d%nTIME: %H:%M:%S"
  DATE: 2012-03-29
  TIME: 11:39:30
  date: illegal time format
  usage: date [-jnu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ... 
              [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]
  </code></pre>
  
  <p>I'm taking that example direct from the man page. What am I doing wrong?</p>
