# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
hpet

If system clcok source is hpet, then gettimeofday will do syscall gettimeofday, not for clocksource tsc. So we should add gettimeofday to seccomp too, otherwise:

2017-12-01T15:16:24 [WARN/seccomp] invalid syscall attempted: gettimeofday(96)
2017-12-01T15:16:24 [CRIT/seccomp] invalid syscall not allowed: stop here

Reproducible: Always
