I just wanted to add this here as I use this docker image and found a temporary solution to the problem. The symlnk for /etc/localtime is pointing to /usr/share/zoneinfo/Etc/UTC This is where the graph generation is coming from. Running ./poller.php -d there is a timezone section, this will confirm that the docker image set the TZ vars for the system correctly as well as php and mysql. rm /etc/localtime; ln -s /usr/share/zoneinfo/America/New_York /etc/localtime (for example) As long as your TZ is America/New_York Will fix everything; until you restart your container..
