You'll need a pmtime(1) binary built from git master installed.

OK, I'll check out pmdumptext today, but possibly similar root cause.

You need a bit of client side logic, yep - a callback function or two and
usually special-case handling for gui-mode inside the fetch loop.  See pmval
code around opts.guiflag and the pmTimeControls data structure.

I've found it to be handy in the past for scanning around quickly in large
archives using pmval - so, yep, could make sense for pmrep.

cheers.
