> How do I add a 'date' widget ...
The xclock executable I have is under /usr/X11R1/, so not from pkgsrc. You can specify -analog or -digital but I only get one or the other display with the standard build.
/usr/pkgsrc/time/catclock is very nice.
A while ago, I modified xchrono to include additional displays for various time zones/locations. I think those are analog only displays.
