Set server timezone to UTC

[jasonmcneill]

In production a typical server will be configured in the UTC timezone. But on local the status quo uses the timezone of my dev machine. This causes dates and times in my client side apps to be off, and it’s confusing for me to remember that. I or other contributors to my application may unnecessarily add offsets in code which only complicates matters when such code gets pushed to higher environments. I’m just trying to mimic on my localhost the conditions of a typical Web server as closely as possible.
