How come a $1500 computer can't keep accurate time like my $5 clock?

Heres the article by the National Institute of Standards and Technology... it clearly states your PC sucks at time keeping. I invested a lot of time at this problem, because 1 second pc time is not 1 second atomic clock time, and PC clock are so whack, automated trading and execution program get affected.

Temperature affects your pc clock keeping and many other things.

I spent 300 on a pci clock because time keeping in pretty important to me..

I've been running PCs since the days of the XT and have had at least a dozen of them (probably double that) in that time period. All sorts of motherboards and configurations. All kept time horribly without running something like atomic clock. And yes, I've replaced CMOS batteries at least a half dozen times (for other reasons) with absolutely no effect on the time keeping ability.

It's remarkably simple for a cheapo plug in clock (either mechanical or digital) to be 100% accurate (for consumer needs). It dumbfounds me that computer designers & builders can't accomplish this simple task. To be its an embarassment, to the designers, it must be superfluous.

Its not the battery, its the clock itself.. the old days, I had to buy real time clock chip.. ie the most famous dallas real time clock.. this was the 8088 days, before xt came out

Holy crap... I would've used it to buy some Ipod like device.

Seriously, just replace the cmos battery.

How did you become elite with such dumbass replies?

LOL

Well, that's a pretty weak excuse. For alot of things it's more important for my computer to keep accurate time then a $5 walmart watch.

what do you mean that's weak? out of a $1500 computer there's a $0.25 oscillator and a $1.00 battery to keep time for you. the rest is all pure processing and storage.

I mean that it's important for lots of things that a computer keeps accurate time, so it'd be nice if they did a better job at it and you didn't need to rely so heavily on things like NTP or external signal references, etc.
