Container time should be same timezone as user

[rfay]

What happened (or feature request):

It's hard to read and understand logs from the containers as they're in GMT. It would be pretty easy to set them to be the same as the host timezone (I think).

What you expected to happen:

How to reproduce this:

Version: Please include the output of ddev version, docker version and the project's .ddev/config.yaml.

Anything else do we need to know:

Please use a complexity rating of 1-5 (5 is high) for a feature request. (High complexity implies more PR planning)

That's reasonable. Looks actionable as is.

So far this isn't as easy as I would have thought.

• The method of getting timezone on the host varies (mac requires sudo: sudo systemsetup -gettimezone
• The discussions in https://serverfault.com/questions/683605/docker-container-time-timezone-will-not-reflect-changes deal directly with this, but unfortunately assume a known timezone, which we don't know at image build time or even seem to have a good way to get it predictably on all platforms.
• Golang's zone response doesn't include the correct offset during DST.

	t := time.Now()
	tz, offset := t.Local().Zone()
	if offset < 0 {
		offset = offset * -1
	}
	zone := "XXX" + strconv.Itoa(offset/3600) + tz

I know this wouldn't work with tail, but would it be crazy to address this as a regex replacement at the time of output? That seems silly that macOS requires sudo just to know timezone... I can't see how that would be a security attack vector.

[rfay]

There are so many different kinds of output that it's too painful to imagine. And people like me may want to work inside the container and see reasonable times.

[rickmanelius]

Completely fair. I was spitballing. Looks like we're then blocked unless/until this gets addressed upstream, correct?

[rfay]

Not blocked, just frustrated. It's probably solvable, might be slightly more effort than I expected. I was just trying to write down what I learned.

Most people don't need this, and for the ones that do there's a super easy workaround adding a $TZ environment variable, https://stackoverflow.com/questions/50255466/how-can-i-set-the-timezone-in-my-ddev-containers/50255467#50255467 - I think this is better than adding extra code to our codebase.
