Clojurians Log v2

Any idea how to set timezone for the deployment? I followed the https://biffweb.com/docs/tutorial/deploy/ (to linode) I changed UTC to IST in deps.edn :biff.system-properties/user.timezone "IST") - but I after some tinkering I think this is for something else but I still see the timestamps from logs and (t/now) from tick library, are in GMT timezone. In local it works as expected, so I'm guessing it has do with system settings? Is there a way to set it before I start fiddling with environment
