It works fine here. I've tried to reproduce what you see using
different settings, but have had no luck.
Can you give me some more information? Maybe generate a raw URL for
the clock and paste it back here (even a short-URL would work, I can
distil the needed information from that too). With a bit of luck that
should give me enough information to reproduce the issue you are
having.
If it does what you say, I'd really like to fix it asap.
Thanks,
Otto
