title: How to get list of all EBS Snapshots "started" before a certain date?
body: <p>I am writing a Python program to get a list of all the EBS snapshots in our account (owner=self) that were "started" (basically, created) before a certain date, then perform some other actions on that list.</p>
  
  <p>I don't think I can use filters in the get_all_snapshots() function because it only supports equality, not GT/LT operators.  I believe <a href="https://stackoverflow.com/questions/24891834/aws-boto-get-snapshots-in-time-period">AWS boto Get Snapshots in Time Period</a> confirms this.</p>
  
  <p>So I supposed I have to get a list of all of them, then iterate through the list.  However, the boto documentation isn't clear to me (<a href="http://boto.readthedocs.org/en/latest/ref/ec2.html#module-boto.ec2.snapshot" rel="nofollow noreferrer">http://boto.readthedocs.org/en/latest/ref/ec2.html#module-boto.ec2.snapshot</a>) exactly what methods/properties are available on the snapshot object.  </p>
  
  <p>Any guidance here? </p>
