[Bug] Context broker does not respect DateTime timezone

[jmcanterafonseca]

how to reproduce:

create an entity with an attribute of type DateTime coded as an ISO8601 string, for instance

2016-11-01T19:00:00+01:00

Perform a query which lists the referred entity. The attribute value is now expressed incorrectly in UTC:

2016-11-01T19:00:00.00Z

As far as I understand by https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators, the following timezone designators should be supported

<time>Z
<time>±hh:mm
<time>±hhmm
<time>±hh

But not strings like "UTC", "CET", "PDT", etc.

Is my interpretation correct?
