eventTime format wrong

The date format of the eventTime field is not appropriate:

actual format: "eventTime": "2017-12-11T13:36:01.263944+0000"

expected format: "eventTime": "2017-12-11T13:36:01.263944+00:00"

this is the part of the CADF spec. that is relevant:

6.3.4.3 Requirements
1601 This specification defines a Timestamp type that is based upon the xs:dateTime as per XMLSchema2. Any entity
1602 (or property) value that represents a Timestamp type in this specification, its extensions, or profiles SHALL adhere
1603 to the following requirements:
1604 Syntax requirements
1605  The dateTime portion of Timestamp typed values SHALL adhere to the Lexical representation as per
1606 XMLSchema2, clause 3.2.1.7 "Lexical representation".
1607 Lexical representation:
yyyy '-' mm '-' dd 'T' hh ':' mm ':' ss ('.' s+)
1608  The Time Zone Designator (TZD) portion of the Timestamp typed values SHALL adhere to the Lexical
1609 representation as per XMLSchema2, clause 3.2.7.3 "Timezones" and SHALL always be expressed as a UTC
1610 offset.
1611 Lexical representation:
('+' | '-') hh ':' mm
1612  The character 'Z' for Time Zone Designator (TZD) SHALL NOT be used. If a Timestamp typed value indicates
1613 an event action that actually occurred in a region where the local time UTC offset is actually zero (or 'Zulu'
1614 time), a following fully qualified TZD SHALL be used.
1615 Example:
('+' | '-') 00:00
