If you are situated West of UTC you might be running into the timezone issue I reported. The work around I had was to change this line<https://github.com/peeringdb/peeringdb-py/blob/289524928c62115da114a0a05e591c940b03ac4f/peeringdb/_update.py#L97> in peeringdb/_update.py
from
self.start_time = datetime.now()
to
self.start_time = datetime.utcnow()

Arnold Nipper said to send to this list.
(This is kind of urgent for me, my goal is to get a snapshot of the data, so any alternative workaround would be helpful in the meantime.)
I'm in the process of setting up a local copy, and have run into a problem after getting the peeringdb-py stuff set up.
When I do peeringdb sync (with the correct mysql database UTF8 stuff and everything,), I am currently getting a persistent error which aborts the sync with no data in the tables:
(Apologies in advance for the long error output text.)

Please let me know if this is a problem on my end, or a problem with the data in the master db itself...
If there is something I should do to fix this on my end, any advice would be greatly appreciated.
(If there is any other way to grab a copy of the tables in mysql format, that's all I'm really trying to get, just a snapshot of the current peeringdb database to process with some perl scripts I have.)
Thanks in advance,
Brian Dickson
