dateutil.parser._parser.ParserError: Unknown string format

[iphoting]

Hi,

It looks like tarsnapper breaks when the job name has more than one -:

$ /usr/local/bin/tarsnapper -c /opt/tarsnap/etc/tarsnapper.conf list

Error snippet:

Ignoring '/xxx/snipe-it-db-20210121-222959': Unknown string format: db-20210121-222959
Traceback (most recent call last):

  File "/usr/local/lib/python3.7/dist-packages/tarsnapper/script.py", line 254, in parse_date
    return dateutil.parser.parse(string)

I have same issue. Could be that python version compatibility issue ? I'm using python 3.9
