I have the following timestamp element:

<timestamp key="compactTimestamp" datePattern="yyyyMMdd'T'HHmmss'Z'"/>

for use in a file appender:

<file>${LOG_DIR}/translator-${compactTimestamp}.log</file>

Note the `Z' in the date pattern. However, the date that is generated is in local time. It would be preferable to have a GMT option as found in the pattern element:

<pattern>%-80(%d

{yyyy-MM-dd'T'HH:mm:ss.SSS'Z',GMT}

%-5p [%t:%C

{0}

.%M]) %m%n</pattern>

I am working around this by starting the VM with -Duser.timezone=UTC.
