Timestamps: incorrect timezone and format

[mmd-osm]

Timestamps always have to be returned in UTC-0, with a "Z" at the end. Currently, yalcha returns times in UTC+03:00 timezone, without a time zone indicator:

https://vheirh41ic.execute-api.us-west-2.amazonaws.com/development/api/0.6/node/21265449/history

timestamp="2017-11-29T13:16:22"

https://api.openstreetmap.org/api/0.6/node/21265449/history

timestamp="2017-11-29T10:16:22Z"

yes, a 'Z' needs to added to this constant

yalcha/osm/helpers.go

Line 10 in 7bea019

const osmTimeFormat = "2006-01-02T15:04:05"

and probably some .UTC() added to the timestamps after they are loaded from the db. But it might be easier to just run the server in UTC.

You probably want to set your timezone to UTC when connecting to postgres
