Maybe jQuery is overwritten by another widget, so it loses it's TimeCircles function. From what I see at the repository, it should properly work. Maybe file an issue here; https://github.com/chadevansMX/Counter and add a stacktrace of the error
I looked at the widget repository and it seems that the problem have been identified. Maybe the fix never worked...
Need to have a unique load of jquery so that there is no conflicts with other widgets.

I have updated the structure in a fork of this widget, see this comment. Could you test this one? I basically used the same trick we did in the Lightbox widget when it comes to dependencies.
