Clock Loses Time

**TonyPSchaefer** · 09-08-2009, 09:39 PM

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 =
