Is letsencrypt running twice?


I have two logs for letsencrypt:
letsencrypt.log and renew.log

They have different times in them and I was wondering if the update was running twice. I run a cron update script at 0100, but the letsencrypt.log says an update ran at 0600. Can someone tell me what is going on here?

The following certs are not due for renewal yet:

No renewals were attempted.

Given that the timestamps are exactly the same (down to the miliseconds) other than the hour, this does seem like a timezone issue. I’d suspect one of the log files is using UTC (I seem to recall that the client defaults to UTC for letsencrypt.log), while the other uses your system timezone. Does that account for the 5 hour difference?

Not sure if there’s a good reason for why it works that way. Out of curiosity: Is this a OS-packaged version of certbot (like the one in debian backports), or are you using certbot-auto?
