Hi,
You have to enable CONFIG_FEATURE_SUID with /etc/busybox.conf option active.
Do a chmod u+s /bin/busybox (root.root)
Create a /etc/busybox.conf file containing
----
[SUID]
hwclock = ssx 0.0
----
then a normal user can run specified command with root rights
and $ hwclock -w works for me.
kind regards.
