Date test fix attempt #2

[tkroman]

Fixes #16 now

[jexp]

I'm still scared to try it out :) could you rebase it and we'll see if travis gets green?

[tkroman]

@jexp I accidentally committed with the incorrect accoun/emailt, so there's a weird commit history now. Considering you mostly accept this in a manual fashion, would that be a problem?

UPD. Travis seems to be OK with my changes. Yay.

@tkroman What's the status, do you want us to merge manually ?

[tkroman]

@ikwattro If that will make git log look prettier than it would look otherwise (which I think it will). Anyway, there might be conflicts with #43.
Most importantly, note that this PR not only brings test fixes, but also switches to a ZoneId#getDisplayName(), which should be more reliable and environment-independent than now.

@tkroman I looked at your change in this PR. As I didn't make any changes in the same area, I don't expect any conflicts. 😄

PS: Disagree with manual merge. It's best to preserve attribution through pull request merges. Maybe in exceptional cases, manual merge can be done providing correct author attribution. However, I recommend against it being standard practice.

[ikwattro]

I tend to agree also. I prefer to keep history, or ask the author to squash itself.

[ikwattro]

I'll check with the team about merging locally / squash etc. For now I followed what was done by MH until now. Thanks @ADTC and @tkroman for your contributions.

@ADTC I'm not aware about the releasing policy yet, however I can send you the jar via PM on Slack.
