Always run production systems in the Etc/UTC timezone. This eliminates an entire class of problems while only creating minor inconveniences.
I work for a company with servers, employees, and customers in basically every time zone around the world. And yet every server, internal tool, and workflow uses Pacific time. UTC is used precisely nowhere. Setting aside the issues of DST, I imagine it's convenient for the employees and managers in HQ but absolute madness for everyone else.
Are you at Google? Because they also keep using US/Pacific timezone in every incidents where it affects everyone over the globe
