Ah! Thanks for the direction. But it is not efficient, isn't it?
Similar to

    timer->repeat = 30.;
    ev_timer_again (loop, timer);

instead of

    ev_timer_stop (loop, timer);
    ev_timer_set (timer, 0., 30.);
    ev_timer_start (loop, timer);

"This is slightly more efficient then stopping/starting the timer each
time you want to modify its timeout value, as libev does not have to
completely remove and re-insert the timer from/into its internal data
structure."
