title: What is the unit of time in MySQL's slow-query log?
body: <p>I'm looking at the slow query log from a drupal-based webapp, and have lines that look like this:</p>
  
  <pre><code># Query_time: 3257  Lock_time: 0  Rows_sent: 272  Rows_examined: 272
  # Query_time: 1654  Lock_time: 0  Rows_sent: 222  Rows_examined: 222
  # Query_time: 3292  Lock_time: 0  Rows_sent: 269  Rows_examined: 269
  # Query_time: 1029  Lock_time: 0  Rows_sent: 172  Rows_examined: 172
  # Query_time: 2126  Lock_time: 0  Rows_sent: 251  Rows_examined: 251
  # Query_time: 1731  Lock_time: 0  Rows_sent: 229  Rows_examined: 229
  </code></pre>
  
  <p>Are these times indicating that the associated queries took between 1 and 3+ seconds (slow but not terrible) to execute, or between 1,000 and 3,000+ seconds (completely unacceptable)?  I understand that the <code>long_query_time</code> option is specified in seconds, but do the log messages follow this same convention, or do they use milliseconds instead?</p>
  
  <p>Edit:  this is with MySQL version 5.0.45.</p>
