I think a timer in Basic is feasible to be accurate within .05 seconds. This is my idea (some errors to be worked out but it gets the idea across)-

Code:
``` ClrHome ­1→Q 0→T 0→A 0→O 0→P 0→U 0→S 0→D Output(5,4,"PRESS ANY FOR START" Repeat Ans   //waits till button is pressed getKey End ClrHome Repeat not(C)+(startTmr=A)+getKey O+(P-T→O   //O is the offset between the start of a second of the RTC and where you pressed the button... in ticks If Q=0 33-P→O  //33 is the estimated ticks/ sec for times under one second P→T O While (Ans>0)not(getKey   // counts down offset Ans-1 End Ans→D Q+(Ans=0→Q U+P+(O-D→U Output(5,13,Q D=0→C 0 startTmr→A  While Cnot(getKey)(startTmr=A // waits till RTC changes and counts ticks till then Ans+1 End Ans→P End ClrHome //calculate Seconds Output(5,12,S ```

I've been yelled at a lot on SAX for this please give me your logical, well reasoned thoughts below. And feel free to ask any questions about the code
Readable code, which is run a few times to get an "average" of the "sub-second" time offset.

Code:
```// Mateo Note: This is the core of the program: 0->B startTmr->A While startTmr=A    // Mateo Note: This is asynchronous. The RTC will never align at the same PC every loop B+1->B End // Mateo Note: He tries to use the B variable as the new "sub-second time" offset.```
A timer in basic IS possible, just not how you're trying to do it. Misleading title.
As Mateo said, you just need to get an average time (over many runs) since the 1-second accuracy of the time functions isn't very accurate. But regardless, you could just use an asm timer like this one which will be wayy more accurate.

EDIT: This was not what Mateo was trying to say.

I didn't say that. I just said what his code is doing. It isn't accurate at all, and it won't work for multiple reasons. Of course, he won't listen to me, so I no longer feel like answering any of his questions.
