mod_client_management: Show grant expiry in shell command
I want to know when my OAuth2 grant expires and that it really is
extended by refreshing.
module:set_global();
local log = _G.log;
module:add_timer(60-os.date("%S"), function (now)
log("info", "-- MARK --");
return 90 - ((now + 30) % 60);
end);
