Currently, when creating a View in Zendesk Support, the only optional SLA clock column is "Next SLA Breach" - and by default, it shows the "Requester Wait Time" clock (after the "First Reply" is sent).
It would be extremely helpful if the choice was given to the View creator which SLA metric to display in the View column they create.
You can try to check our Time Tracking recipe Update handling time by agent.
