It is simultaneously 4:00 and 8:00 in this temporal anomaly from Serbia, documented by Bicanski.  We might note a bit of irony: although time at that clock tower is unstable, the numbers four and eight happen to be symbolic of stability, symmetry, and squareness in Chinese culture.  Though we weren't on location to discover the exact cause of this timely weirdness, we offer this photo to help hone the insights of would-be investigators of temporal anomalies.  The more clocks one sees that are "on the fritz" (Fritz being the German clockmaker who first went "cuckoo"), the better attuned one will be to time warps in the wild.
