Through my activities elsewhere, I've been comparing the time standard on my HDR-FOX (note - not the HD-FOX sans aerial avec Internet time source... how many G points does that get me?) with MSF Rugby (one of the sources of atomic time which radio-controlled clocks pick up). Rugby agrees with the pips on analogue radio (digital radio runs about a second behind mainly due to the decoders in the receiver - pips will be pointless when they turn off analogue). Curiously the clock on my RDS radio is a second fast! The time display on BBC NEWS is also within a few seconds (3 in my case, again there are digital decoder delays in the path). It's a different story with my HDR-FOX I-Plate and screen saver clocks though. I have measured them as 31 seconds fast. This presumably has implications for manual timer recordings and padding recordings, also for any time logs used in the custom software. It would be useful to get a survey over a selection of HD/HDR-FOXes, and also over a period of time. Bring up the screen saver clock by pausing a live channel and waiting a few minutes for it to appear (this gives a six-digit representation of system time) and compare it with atomic time or analogue pips, then post your results.
