I'd like to have the current time in my
tmux status line. I got as far as:
$ tmux set status-right '"#22T" %H:%M:%S %d-%b-%y'
This does alter the time in the status line to include seconds. However, the status line is only updated if "something happens": I switch windows, switch panes, etc. How can I configure tmux to update the status-line every second, so that I can have a running clock?
