Show duration when task (task step) is running

[say5]

Feature request

Currently duration in UI is shown after the task (or task step) is complete.

For long running processes it would be nice to see current timing.

Thanks for the feature request @say5. This is something we used to have, but removed at some point due to inconsistent / unreliable timestamps coming from the PipelineRun / TaskRun resources while they were in progress. We can revisit to see if this has improved in more recent Tekton Pipelines releases.
