Hey @potvinp
Yeah that is strange,
Have you seen this?
I havent had any issue with timezones but I also havent used UTC. it seams you hit all the timezone spots but what I dont under stand is the Server config shows UTC -4 and the web browser.
UTC -4 is the east coast of USA. kind of odd because Opensearch/Elasticsearch uses UTC by default and the other configurations are within the configuration file.
Something wasnt configured correctly and it hard to see from here. You are correct this is the reason why you have this issue its with timezone out of sync 100%
EDIT: I came across this old post
