Python client prints wrong timestamps to fetched data

[Mikkolehtimaki]

Run the query to get data for 8.8.2018 14:00.

./fmiopendata --stored_query=fmi::observations::weather::multipointcoverage --bbox=19,59,20,60 --start=2018-08-08T14:00:00Z --end=2018-08-08T14:00:00Z data

Result displays data as '2018-08-08T17:00:00', which is a three hour offset. Reason seems to be the timestamp conversion function.

The correct function to use should probably be (in python 3.7 at least)
temporal_pos = datetime.datetime.utcfromtimestamp(timestamp)
