what is a pll clock generator?

With the goal that a clock signal will not drift, \nPLL (phase locked loop) logic can be added to keep\nthe frequency constant.  It works by adding "feedback"\n(from the output back to the input) with a tuning\ncircuit to keep the two signals (the original input\nas well as the feedback) in synch.

Your clocks jumped *automatically*???  DANG!!!  I spend an hour twice a year resetting all of mine!  It takes me so long because I can never remember how to do the ones on the stove, the microwave, and in my car, so I have to RTFM's (that's "read the {bleeping} manuals") every single time!  I'm green with envy.  Where do you buy your clocks???

Transistor-Transistor Logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT), and resistors. It is notable for being a widespread integrated circuit (IC) family used in many applications such as computers, industrial controls, music synthesizers, and electronic test and measurement instruments.

yes i don't remember them at this time but u can search for them in desktop utilities or enhancements of many download sites like download.com, freewarefiles.com, softpedia etc.\n\none such clock is called alarmme

Just did a quick google search and came up with this :\n\nhttp://www.amdboard.com/ocspecial.html\n\nI have never really over clocked anything as that tends to shorten its life span since it isnt meant to run at the higher speeds.

Wave shaping circuits are used in function generators.  You might get some help here http://en.wikipedia.org/wiki/Function_generator

here is a script for a javascript clock....\n\nhttp://www.javascriptkit.com/script/script2/digitalclock.shtml\n\nhttp://www.javascriptkit.com/script/script2/analogclock.shtml\n\njust search javascriptkit.com or dynamicdrive.com.

The system clock is set thru BIOS.  Therefore, you'll have to run an external command to set the clock.  \n\nString cmd="time 11:30:00";\nProcess proc = Runtime.getRuntime().exec(cmd);\n\nYou will have to make sure the 'command' is correct; my example is just a guess.

A frequency oscillator.

the device is called a phase sequence indicator.  you connect it to the leads of the motor and rotate it and it will tell you the sequencing of the phases

Try Emperor Clock Company. they have excellent grandfather clock kits.

There's a small round battery located on the motherboard. This battery keeps the time clock as well as your settings going. The battery usually is a CR2032 battery you can get at any department store. That battery is going dead. This is a very easy job on most computers. If you have any other questions you can email me.\n\nstlouisfan

I can tell you about two kinds of timers. One is digital: a high-frequency clock oscillator followed by one or more dividers.  A divider is a counter that counts clock pulses up to N, then resets the count to 0, starts a new count, and sends an output pulse.  This divides the clock frequency by N.  Using dividers with adjustable N values, any number of clock pulses, thus any time interval, can be measured between output pulses.\nThe second kind is analog. A precision capacitor is charged with a constant current. The voltage across tha cap is a "ramp". When this ramp reaches a threshold value an output signal is produced.  The time interval is adjustable by changing the charging current or the threshold voltage.  The rate of change of voltage is dv/dt = I/C, dv/dt in v/sec, I is current in amps, C is capacitance in farads.
