Change Ib0024cce95 intended to include all timer metrics into traces,
but it only captured timer metrics that are recorded by
try (Timer1.Context ignored = metric.start(field)) {
// do something
}
but not timer metrics that are recorded by
timer1.record(field, System.nanoTime() - startNanos, TimeUnit.NANOSECONDS);
