Problem with console timestamper plugin when using workflow

[David Karlsen]

Hi - I'm moving over to jenkins workflow - but the timestamper does
not seem to work here?
I have this config:
node ('docker') {
wrap([$class: 'TimestamperBuildWrapper']) {
.....
}}

and it fails with:
java.lang.UnsupportedOperationException: no known implementation of
class jenkins.tasks.SimpleBuildWrapper is named
TimestamperBuildWrapper

the plugin is installed - it works fine in non-workflow type jobs.
