When

"-Dorg.apache.commons.jelly.tags.fmt.timeZone"

is set, choosing "System clock time" option in side panel doesn't show timestamps in system clock timezone, but in the timezone set by "-Dorg.apache.commons.jelly.tags.fmt.timeZone".

Current behavior:

having:

      "-Dorg.apache.commons.jelly.tags.fmt.timeZone=UTC"

and sytem timezone set to EEST:

      (/etc/localtime -> /usr/share/zoneinfo/Europe/Helsinki),

timestamper plugin shows timestamps in UTC.

Expected behavior:

• "System clock time" should generate timestamps in EEST

• There should be another radio button with the option like "Use timezone from jelly.tags.fmt.timeZone (UTC)"
