Installed from:    Compiled sources

Using KDE 4.2 RC1 on Kubuntu.

If I have a digital clock plasmoid in the panel set with minute
resolution (so, no seconds displayed) and I change the clock by another
mean (say, ntpdate), the clock won't be update until the next minute
comes.

So for example if I have my digital clock showing 10:02 AM, I run
ntpdate and I get my system date updated to 10:05 AM, the clock will
still show 10:02 for about a minute, then it jumps to 10:06.

In order to fix this cases, the plasmoid should retrieve the engine data
always at 1000msecs or use the default setting and "detecting" that kind
of changes (>1 minute of difference), do know if the last is possible.

waking up once a second to catch what minute it is would be excessive;
we try and minimize wake ups.

as far as detecting time changes, that's probably the way to go (and
should happen in the engine) ...

after further looking around, it seems there is no reliable way to get
notified of system updates that are done "behind our back" without
polling, which really isn't an option.

what we can eventually do is limit the pain, as we do with time zone
changes, by having kded emit a dbus signal whenever the time is changed
the date and time control panel.

sounds like a nice thing for 4.4 (along with putting the date and time
panel in the clock config itself :)

btw, the kernel recently got timer notifications enabled. So we can sign
up for a signal when the kernel's time itself gets changed and change
time when that happens, preventing wakeups. As far as where this is
going to be implemented, I thought I heard somebody mention about
implementing it...
