UPS Masters Time Travel

It would appear that UPS have mastered time travel (click the image for a larger version if you can't read the small text).

I'm guessing that actually they simply recycle their old tracking IDs, but you would think they would clear out the old information before hand. The status of my parcel has now changed from "Delivered" to "In Transit", although the shippment progress section still shows the delivery to Croydon. Hopefully it will actually arrive in Penistone on the 11th as promised, otherwise finding it could be a tad tricky!
