title: Chance on generating 2 equal hashes based on time()?
body: <p>Question is pretty simple, but I couldn't find an answer for this one... Basicly, my application is generating filenames with <code>md5(time());</code>.</p>
  
  <p>What are the chances, if any, that using this technique, I'll have 2 equal results?</p>
  
  <p>P.S. Since my question title says hashes not exact hash, what are the chances, if any, again, of generating equal results for each type of hashes <code>sha1();</code>, <code>sha512();</code> etc.?</p>
  
  <p>Thanks in advance!</p>
