Tell trace-cmd that the "tai" clock source should be displayed in seconds
and needs to be parsed as such.
Instead of:
sleep-2084 [001]1651097314396951318: function: __mutex_unlock_slowpath
sleep-2084 [001]1651097314396951516: function: ktime_get_mono_fast_ns
sleep-2084 [001]1651097314396951773: function: ktime_get_mono_fast_ns
sleep-2084 [001]1651097314396951773: function: rcu_read_lock_sched_held
sleep-2084 [001]1651097314396951949: function: ktime_get_mono_fast_ns
sleep-2084 [001]1651097314396952359: function: ktime_get_mono_fast_ns
Display as:
sleep-2084 [001] 1651097314.396951: function: __mutex_unlock_slowpath
sleep-2084 [001] 1651097314.396952: function: ktime_get_mono_fast_ns
