XbpToolBar() is using Microsoft Common Controls as activeX and have no 
Ownerdraw so you can't use Pablos Tricks.

when :addItem() => oButton Object
you can change oButton:caption with TIME() within a Thread

p.s. to show TIME i recommend to use Statusbar

i had a deeper look to Pablos Class Code : it will display Time in Titlebar 
on right Side ... but only in Win XP you can see it
Titlebar Area since Vista are under Control of DWM and use 
DwmExtendFrameIntoClientArea() to paint.

but you ask for Toolbar so just adjust Position of rc

IF VAL( OS(OS_VERSION) ) < VERSION_VISTA
  now adjust the right end of the rectangle according
  the state of the buttons, we asume the buttons are square
  but with some themes maybe wrong and we must query the theme metrics 
instead
 ...
ELSE
   rc[2] += nTbHeight
   rc[4] += nTbHeight
ENDIF

where

#define SM_CYCAPTION 4
FUNCTION xbpGetSystemMetrics( nValue )
RETURN DllCall( "USER32.DLL", DLL_STDCALL, "GetSystemMetrics", nValue )

now TIME() will display on Menubar, Toolbar or what else which is just under 
Titlebar in upper right corner
