I'm using python and boto to get files from amazon S3. I'm uploading with this format: `year/month/FileNameYYYYMMdd.hhmmss.zip`

My problem is that I dont know the time (hhmmss) of the file. There is a way to get it? For example: 

```
bucket = awsCnx.get_bucket(bucketName)
directory = 'year/month/FileNameYYYYMMdd.*.zip'
bucket.list(prefix=directory)

```
