When trying to manually adjust the time in System Settings in KDE4 and pushing "Apply", I got the error msg "Unable to contact the timeserver" (paraphrased from Norwegian).

I then installed openntpd, but it didn't help. I have placed "ntpd" at the end of /etc/rc.conf, and have the following in /etc/ntpd.conf:

"# $OpenBSD: ntpd.conf,v 1.7 2004/07/20 17:38:35 henning Exp $
# sample ntpd configuration file, see ntpd.conf(5)

# Addresses to listen on (ntpd does not listen by default)
listen on *
#listen on 127.0.0.1
#listen on ::1

# sync to a single server
#server ntp.example.org

# use a random selection of 8 public stratum 2 servers
# see http://twiki.ntp.org/bin/view/Servers/NTPPoolServers
driftfile /var/lib/ntp/ntp.drift

server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
server pool.ntp.org"

Judging from /var/log/daemon.log, openntpd is working, but how do I make KDE4 recognize and use it??

What you need it ntp-client, unless you are running a time server yourself.

Care to expand? I am using Arch and cannot find "ntp-client" in Arch's repositories. I thought openntpd would double as both server and client. However, is it really necessary to install extra software in order to make KDE4 accept a manual time adjustment? Can't recall anything like this in KDE3...

If this was indeed an upstream bug and not unique to openSUSE's KDE4 then this can be fixed by updating your KDE4 installation. See this bug report: https://bugzilla.novell.com/show_bug.cgi?id=401847.

Updating to a more recent KDE4 could solve your problem.

Thanks, Guitarist. As I am using Arch Linux, things get updated pretty often and I am probably already using the latest available version of KDE4. Or will soon. Guess I will just have to wait until the bug has been squashed.
