This is my digital clock. I made it with basics and finally descided to put it on this site. It refreshes every 1 second so you don't have to do it yourself.
In the program itself is a little menu, help-file included at option 4, help. You also can set you're own time and date.

In basic

Hm, pretty nice.
Now try creating an analog clock.
(I once did so it's possible)

same here, but with basic if you store a pic and recall it, text gets erased, but not lines, but re-displaying it every frame looked crappy

Not bad if you only erase the lines

I tried doing a clock before in 2001 but I never got able to make it even close to accurate enough. It seemed like adding one single increment loop to a for loop made it too fast instead of too slow.

EDIT: Fixed horrible typo on clock.

That's impressive that you got it able to update every 1 second, accurately.

thanks, and the analog clock: I made one allready, by copying the source from another, but I'm not good with those sin( things and all

So I made an digital cause it's easyer to read

By the way one issue I had in BASIC is that when holding down or pressing some keys, the program slows down slightly (by about 0.1%, but just enough for any clock to get out of sync)

DJ_O, to be fair, the 84+ has a command called startTmr which returns the current date in seconds after midnight, January 1st, 1997. This command relies on the internal crystal timers so it runs at the same speed regardless of what you are doing.

While your program required very careful calibration and command timing, this one can be done with:

startTmr
While 1
Disp startTmr-Ans
End

Well, what I was trying to do was to explain to DJ_O some of the new features of the 84+. DJ_O didn't know about the clock features of the 84+. What happens is that the 84+ has a quartz crystal timer inside of it that allows for very accurate measurement of time. This crystal runs independently of the calculator and it is what makes the system clock work.

DJ_O was rather amazed that you pulled this program off because back in the day, he couldn't use these internal clocks. The 83+ lacked this crystal timer, which meant DJ_O couldn't use any of these routines:

• checkTmr(
• ClockOn
• ClockOff
• dayOfWk(
• getDate
  
• getDtFmt
• getDtStr(
• getTime
  
• GetTmFmt
• getTmStr(
• isClockOn
• setDate(
  
• setDtFmt(
• setTime(
  
• setTmFmt(
• startTmr
• Time
• timeCnv(

(there were a lot more than I expected)

But, as you can see, without any of those routines, writing a clock would be uber hard. I was just trying to show DJ_O that now an easier method exists.
