body: <p>Is it possible not to expire for <code>CacheItemPolicy.AbsoluteExpiration</code> at the specific time? </p>
  
  <p><a href="https://msdn.microsoft.com/en-us/library/system.runtime.caching.cacheitempolicy.absoluteexpiration(v=vs.110).aspx" rel="nofollow">MSDN</a> there is written:</p>
  
  <blockquote>
    <p>The period of time that <strong>must pass before a cache entry is evicted</strong>.</p>
  </blockquote>
  
  <p>As I understand this sentence means that <strong>no less than</strong> the specific time... is it possible if I set 12 hours, but the record will expire (let's say) only in 12.5 hours? (I mean it's not documented, it will take not less than 12 hours, but 12.5 hours is also possible or even more, right?)</p>
  
  <p>for example:
  I set <code>UpdateCallback</code> and <code>AbsoluteExpiration = 60seconds</code> for my <code>CacheItemPoice</code>, in practice it's called once in 80 seconds. (I logged it)</p>
  
  <p>Inside <code>UpdateCallback</code> I set new values for <code>CacheEntryUpdateArguments</code>, I mean new <code>UpdatedCacheItem</code> (the same key and new data) and <code>UpdatedCacheItemPolicy</code> (the same period of time and the same <code>UpdateCallback</code>)</p>
