Workaround: {{%d\{ISO8601\}\{UTC\}Z}} ;)
However, I do agree that by default, the timezone should be printed explicitly.
The current default promotes bad engineering and is the cause of endless
frustration and loss of productivity when working with numerous logs.

> Hi there!
> There might be a small issue with the Pattern Converters regarding Timezone
> management:
> http://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout
> Right now, these patterns:
> * {{"%d\{ISO8601_BASIC\}}}
> * {{%d\{ISO8601_BASIC\}\{UTC\}}}
> Give the same results:
> * {{20160104T204256,048}}
> * {{20160104T204256,048}}
> However, with a deeper look at the ISO-8601 standards, the second one with
> {{"\{UTC\}"}} should properly add the Timezone at the end of the timestamp.
> Reference: https://en.wikipedia.org/wiki/ISO_8601#Times
> {quote}
> *UTC*
> If the time is in UTC, add a Z directly after the time without a space. Z is
> the zone designator for the zero UTC offset. "09:30 UTC" is therefore
> represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or
> "144515Z".
> UTC time is also known as 'Zulu' time, since 'Zulu' is the NATO phonetic
> alphabet word for 'Z'.
> *Examples*
> <time>Z
> <time>±hh:mm
> <time>±hhmm
> <time>±hh
> {quote}
> As of ISO-8601, the results should be one of the following (configurable?):
> * {{20160104T204256,048Z}}
> * {{20160104T204256,048+00:00}}
> * {{20160104T204256,048+0000}}
> * {{20160104T204256,048+00}}
