Root command at startup?

I am trying to add time sync command to my startup script. I tried

sh -c "sleep 40 && gksu ntpd -qg" &

but unsurprisingly it doesn't work. It needs to run ~40 seconds after X started as it is pointless before it connects to wifi.

Syncing the clock without running the daemon
Warning:
Using this method is highly discouraged on servers and in general on machines that need to run continuously for more than 2 or 3 days, as the system clock will be updated only once at boot time.
Running "ntpd -qg" as a cron event is to be completely avoided, unless you are perfectly aware of how your running applications would react to instantaneous system time changes.

What you need is https://wiki.archlinux.org/index.php/Nt … s_a_daemon

With that out of way, gksu is a GTK frontend for su.
You may need to

export DISPLAY=":0"

Maybe your network management tool can run it for you after the net comes up? I know netcfg can do that anyway.

I am using WICD. I doubt it has such capabilities.

As I already know how to run delayed commands from startup script (I run checkgmail and several other programs this way), all I need in essence, is a way to run root-privileged command from startup script.

What startup script is it anyway? .xinitrc or rc.local?
