title: How to grep the logs between two time range
body: <p>I have a log file <code>abc.log</code> in which content is like this when I do a <code>vi</code> on it.</p>
  
  <pre><code>2015-05-28 18:12:00,815 INFO 0x7f6ed23e3700 send_to - recent: 1432861920 from dc:2 client_id: 102
  2015-05-28 18:13:01,024 INFO 0x7f6ed23e3700 send_to - recent: 1432861980 from dc:2 client_id: 101
  2015-05-28 18:13:42,244 WARN 0x7f6ed26e6700 mgr - Failed to upsert data for userid 3589109212161 with value cat and status -2
  2015-05-28 18:14:00,135 INFO 0x7f6ed23e3700 send_to - recent: 1432862040 from dc:2 client_id: 103
  </code></pre>
  
  <p>I want to see the all the logs between this time frame:</p>
  
  <pre><code>2015-05-28 00:30:00 - 2015-05-28 02:30:00
  </code></pre>
  
  <p>So basically whatever logs I have between these time frame I want to see it in the same order in which it is there already. Is this possible to do using grep?</p>
