Version:            (using KDE 4.2.3)
Installed from:    Unspecified

This patch patch adds a feature that I found very convenient in another program to the time adjust plugin.

I'm sorry for the short description, I accidentally hit the Enter button.

This patch assists lazy people like me in figuring out the camera clock inaccuracy. I've found this especially useful when matching photos to a GPS track, where the times should be corrected with second level accuracy. When I go on a photo trip, I usually first take a picture of my GPS unit displaying the time, so I can compensate for drift in my camera clock.

The patch adds a dialog to let the user load a photo of a clock and tell what time is displayed on this clock. The plugin then figures out the camera clock difference and loads these values in the Add/Subtract fields. The rest of the procedure is as usual.

Yep, this would be nice-to-have feature - the clock in digital camera gets off the correct gps time quite soon and the time shift makes a difference for bikers.

Pieter,

Can you update your patch to work against current implementation from svn.

Thanks in advance...
