Tiny clock on KFOR-DT

While it’s hard for me to imagine that someone did this on purpose, it seems that KFOR-DT has decided to put a tiny, black-text-on-white-background digital clock on the far left side of the HD feed it gets from NBC.

I don’t think it’s from NBC because right now, it says “6:56”, and a clock from NBC would likely rotate time zones like every other network clock does. If it didn’t, it would probably be “7:56” (EST).

It’s not my receiver because my DTV HD-21 receiver (and Sony TV) can’t make a clock that looks like this, and because the clock is not in sync with my receiver or TV’s clocks, anyway.

It seems HD-specific because it’s so tiny that it’s barely readable in HD (on a 46″ screen), and when KFOR goes to local SD commercials, the clock vanishes. When they stay with NBC network commercials, the clock remains in place (and is really really freaking annoying on the black sidebars).

So…am I the only person seeing this? If so, what’s causing it? If not, what’s causing it? Why would they do this? Why? Why??
