Date, Time and DateTime do not accept 'Z' as indicator for UTC timezone.
Change types so that they accept 'Z'. This is done with appendTimeZoneOffset("Z", true, 2, 2).
This lead to the problem that all UTC timezones are printed as 'Z', so 00:00 is not printed anymore.
To react onto this it shall be made configurable if Z or 00:00 shall be printed when the type has UTC timezone. This shall be configurable in the PdpConfiguration.
Reading 'Z' and 00:00 does work anyway.
