    Has anyone else noticed the clock keeping time slowly?

    I listen to Cubs games (shut up, Evan) on WGN radio, AM720. Every hour they have the "hourly chime" and about five times so far this season I've had to bump the clock by a minute.

    At first I figured that it was because I was anticipating it. So one time I actually did anticipate it and waited with my finger on the "minute" button until the chime. Then I changed the time as quickly as possible. I figured that I was off by about ten seconds tops. A few weeks later I was listening to the pre-game show, heard the chime and watched the clock. It was quite a while before it changed.

    Anyone else?

    An entire thread about losing...cool!
    Actually, almost every car I've ever had had completely unreliable clocks...but the one in my Prius gets touched only twice per year when I adjust for Day Light Savings time.

    Is this a new problem? (the clock I mean, not the Cubs).

    mine is not accurate either. but i rarely use it other than checking on what time it "might" be. atomic time is great, but i am not that "together" so i basically waste my life in little 5-10 minute chunks by showing up early for stuff.

    Mine has gained nearly a minute, though I didn't note what day I set it.

    Somebody used the cheap quartz crystals.

    My 2007 remains accurate every standard/daylight savings time change.

    It hasn't gained or lost a minute yet between time changes.

    Hi Tony,

    How do you know that the WGN time standard is correct?

    If this concerns you, I think you should use the official US time website as your reference, which is supposed to be accurate within a second and is based upon the National Institute of Standards and Technology reference.

    Yeah, I thought of that, Patrick. Yesterday, which is what reminded me that I wanted to post about this, I was checking it against my phone time. It was behind again but I let it go until I heard the chime on the radio. The phone and the radio were closer together than the chime and my clock.

    The clocks are cheap. Accuracy will vary between units and operating conditions. It's too bad Toyota didn't use the GPS to set the clock, since the GPS has the time accurate to a millionth of a second.

    Well, Tony, if it makes you feel any better, both my Prius and now my FJ have clocks that are inaccurate. My Prius would lose 5 mins a month, my FJ somehow gains 8 mins a month

    Which doesn't change the fact that BacNET = :sick:

    Mine is slow. It loses 1 second about every 6 months.

    Tony,

    Very, very slick... a classic misdirection move. You've got people
    thinking your clock is loosing time.

    Nice try, your clock is correct. IIRC my high school physics, as you
    approach the speed of light the relative time you experience slows
    down. Yeah, the real "problem" is you are screaming around at a
    horrendous speed, well above the PSL. I can't figure out what speed
    that is, but you haven't fooled me.

    [For the techie types, Tony isn't going to admit how fast he's been
    going. But maybe the numbers can be backed out. If Tony drove 50
    hrs a month, how fast would he have to go to "loose" 1 second in a
    month?]

    My question is, what FE/MPG are you getting?

    I suspect there's another little secret hidden here too: there's "stealth"
    at less than what 42 MPH, and then "warp stealth" above 42 MPH.

    Have you discovered "cosmic stealth?"

    For a quartz clock, losing 15sec/month is considered typical.
    Those who have navigation should have very accurate time since it is linked to GPS satellites.
    I have an atomic watch. Absolutely love it. Never have a need to adjust it (not even DST - it does it for you also). You just know that your watch is always accurate within 1 second.

    I almost got away with it, too. Rokeby outed me.

    I have occasionally taken to driving my car at speeds approaching the speed of light, in a vacuum, along the event horizon of a black hole.

    Tony, it's kind of obvious to me that work-related stress is taking a toll on you. My advice? What else?

    Did you look under the seats?
    It will no doubt be in the last place you look.

    It better be in the last place you look since if you keep looking after you find it, you're not that bright. :)

    Back on topic: I find my clock gains about one minute every 6 months.
