The EarthTools API does not seem to always know daylight savings for a
location. This causes the incorrect time and offset to be reported, see issue #445.
To show the problems with the EarthTools API, you can go to http://www.earthtools.org and select "Helsinki". It reports daylight savings time as "unknown" when it started last month, which is presumably the problem.
This commit changes to using the Google Time Zone API, which
knows daylight savings and provides it separately for us to take into
account.
The free API allows 2,500 requests per day, and 5 per second, which
should be more than enough.
