Ivailo Monev 66442e2e68 plasma: reimplement digital-clock applet
the fact that it had issues with calculating the size hints on locale
change was enough for me to look into it, the fact that it required
dataengine to function (draw a few numbers) was enough for me to
reimplement it. also one applet for that (showing a clock) is enough
