wpdev.sh: sync_time_ntp() should use chronyc makestep (maybe not)

[joshschmelzle]

So that this comment doesn't get burried.

sync_time_ntp(){
    echo "Time before sync: $(date)"
    sudo systemctl restart chronyd
    sleep 8
    echo "Time after sync: $(date)"
}

This should use sudo chronyc makestep or sudo chronyc -a makestep to step the system clock immediately rather than restarting chronyd and adding an arbitary sleep period.

I was just testing sudo chronyc makestep on the latest image from an R4 powered via OTG.

I flashed the microSD. Booted the R4 without Ethernet. Connected the USB NIC to the Wi-Fi via wpa_supplicant.

chronyc makestep wasn't stepping the time to the current time correctly, but restarting chronyd did.

I got the exact same behaviour on M4 as you @joshschmelzle. Decided to restart the chronyd service instead, which worked just fine.
