Use of .GIF on hour hands

When I insert an image for the second hand and it is a static raster format, I have no problem.
But when I try to insert an animated .GIF into it, I get this error message.

error_in second

Do you know if an animated GIF can be inserted as part of an analog hands?

I was able to add a simple .gif for a second hand in GWS but if it really ran or not I do not know.
