Shows how long an initd task took, for example:
procd: stop /etc/init.d/dropbear running - took 0.088824s
procd: Update service dnsmasq
procd: Update instance dnsmasq::dnsmasq
procd: running /etc/init.d/dnsmasq running
procd: start /etc/init.d/dnsmasq running
procd: stop /etc/init.d/dnsmasq running - took 0.092586s
v2: rename variables, correct time unit
v3: use CLOCK_MONOTONIC_RAW to prevent issues with NTP and adjtime
