Just wondering here, as the help topics don't explain it...

How does the TIMER() command return milliseconds? IE, does it return how many milliseconds since your computer's been on, or does it record how many milliseconds since mid-night, etc.

Just curious, as I would like to avoid any pitfalls I may encounter when trying to determine elapsed time using the TIMER() function. Thanks!

You can fool some people some of the time, but you can't fool all the people all the time.

I think it just takes the time (hours:minutes:seconds) in miliseconds.

If you want to have something happen at a steady interval, do something like this

Image All,

I has suspected it took it from: (hours:minutes:seconds)

But what if the user runs thatcode around mid-night (like, from 11:59 to 12:02).

Wouldn't:
timer()-Time

Produce in-correct results right as mid-night hit?

Perhapse, but I don't realy know what the timer() function recieves exactly either Either way, it wouldn't crash or anything, just never perform the task again unless


That way it resets Time if the timer minus Time is less than zero, reseting the Time variable also.

Alright, thanks for the tips.

I suppose I could do a simple check, like, if timer()-time < 0, add the number of milliseconds in a day (I think 86,400,000??) to even it out, or something like that.


Thanks again!

i always thought the timer measures miliseconds since the program started and just continued going up it shouldnt really matter depending on what ur using it for

It's the milliseconds since the computer has been turned on. I doubt it goes back to zero unless you reboot.

Never was sure with this one, DB's help page doesn't actaully say, and the timer function in visual basic returns milliseconds since midnight...

...maybe one day I'll finish a project
