what does Timerinit() timestamp represent?

[martin]

That's exactly what I'm trying to say. I've been told it returns ticks and I've been told that ticks = milliseconds I don't know what the heck ticks are, or even if the timestamp is in ticks. What I really want to know is how to turn the timestamps into milliseconds or seconds even. I want to be able to manipulate the timestamps do math on them and all that, but to do that I need them in some variant of seconds (seconds or milliseconds)

I'm thinking of totally giving up on timerinit() and useing _datediff('s', x, y)

The help file is pretty useless in this case, it says it returns a timestamp in milliseconds which it does not. There is 2 things that I want to do:

1) be able figure out the ammount of time between 2 timestamps

2) be able to add or subtract time from a timestamp

So i take a timestamp and if 10 mins passes then i do something But if I pause the script using my custom tray pause another timer is started and when its unpaused i run timerdiff() to see how long it was paused for then I want to add that time to the original timestamp so that the time its paused for doesn't count towards the 10 mins There are some other things I want to do but this is the biggest problem I'm running into. Since I don't know the units of the timestamp, I can't manipulate it. I thought it was in milliseconds, but it didn't work as it was supposed to.

I don't understand your problem perhaps because although I agree that TimerINit() doesn't return mS, I don't see it's a problem because you only need to use TimerDiff.

If you want to measure time since event A then at event A you say

$EventA - TimerInit()

Then the time since event is is always TimerDiff($EventA)

If there is a second and third event then

$eventB = TimerInit()

$EventC = TimerInit()

Then, if you want to know the time that has elapsed since A, but discount the time between B and C you say

$TimefromAlessBtoC = Timerdiff($EventA) -(TimerDiff($eventB) - TimerDif($eventC))

I feel dumb but perhaps someone can clarify. According to Wikipedia, a tick is a fraction of a millisecond.

http://en.wikipedia.org/wiki/System_time

They have a chart showing the resolution of various languages time functions.

[SmOke_N]

Yes and that is what the OP has been saying all the time as as I have understood it.

@Smoke_N

The point is that if TimerInit() returns a time related to mS since the last boot then the difference between the returns from two TimerInit() calls should be equal to the time between the calls in mS. It isn't. So when the Help says that TimerInit() returns a timestamp in mS what does it mean by a time stamp? On two PC's I've tried I get about 3500 times the number of mS (approx).

I guess I am just not following the thread.

In other languages, I use QueryPerformanceCounter and QueryPerformanceFrequency. I probably got that idea from AutoIt lol... having said that... not quite sure where everyone is getting that TimerInit() uses time since last reboot (aka: GetTickCount ).

Well there is this old thread here:

Well there is this old thread here:

And then there's old source:

AUT_RESULT AutoIt_Script::F_TimerInit(VectorVariant &vParams, Variant &vResult)

    vResult = (double)now;

    return AUT_OK;

} // TimerInit()

Eureka?!?!

What is «2394049.99993096»?

What is «2394049.99993096»?

I don't know how I figured it out but...

$tick = TimerInit()/TimerDiff(0) ;$tick = 2394049.99993096

;Convert milliseconds to Years,Days,Hours,Minutes,Seconds,Milliseconds
TimerConvert(TimerInit()/$tick) ;Uptime
TimerConvert(TimerDiff(0)) ;Uptime

Func TimerConvert($timestamp)
    $milliseconds = $timestamp
    $years = Int($milliseconds / 31536000000)
    $remainMS = Mod($milliseconds, 31536000000)
    $days = Int($remainMS / 86400000)
    $remainMS = Mod($milliseconds, 86400000)
    $hours = Int($remainMS / 3600000)
    $remainMS = Mod($milliseconds, 3600000)
    $minutes = Int($remainMS / 60000)
    $remainMS = Mod($milliseconds, 60000)
    $seconds = Int($remainMS / 1000)
    $remainMS = Mod($milliseconds, 1000)

    $format = StringFormat("%s years, %s days, %s h, %s m, %s s, %s ms",$years,$days,$hours,$minutes,$seconds,Int($remainMS))

I don't know how I figured it out but...

$tick = TimerInit()/TimerDiff(0) ;$tick = 2394049.99993096

I get a slightly diff value when I run that, so it must be system specific. Is there any way I can find the code for the timerdiff function and see how it figures it out? What file do I look in to find the code for that?

Like a dog chasing your tail here.

///////////////////////////////////////////////////////////////////////////////
// TimerDiff(Baseline)
// Takes the time difference between now and Baseline and returns the result.
///////////////////////////////////////////////////////////////////////////////

AUT_RESULT AutoIt_Script::F_TimerDiff(VectorVariant &vParams, Variant &vResult)
{
    __int64 freq, now;

    if (!QueryPerformanceFrequency((LARGE_INTEGER *)&freq))
        return AUT_OK;

    if (!QueryPerformanceCounter((LARGE_INTEGER *)&now))
        return AUT_OK;

    vResult = (((double)now - vParams[0].fValue()) / (double)freq) * 1000.0;

    return AUT_OK;

} // TimerDiff()

Not a fan of magic code, the example I posted before in post 5 should have sufficed (if not at least the dll call) for what you are attempting.

Smoke posted timerinit() I'm looking for timerdiff() to see how it changes from ticks to milliseconds or whatever it does.

Edit: Nevermind, I didn't see the next page as i was responding to this

Might be able to utilize this one timeGetTime to suit your needs.

Dim $nTimeStart = _TimerStart()
While 1
    ConsoleWrite(_TimerCheck($nTimeStart) & @CRLF)
    Sleep(100)
WEnd

Func _TimerStart()
    Local $atGT = DllCall("Winmm.dll", "dword", "timeGetTime")
    If IsArray($atGT) Then Return $atGT[0]
    Return 0
EndFunc

Func _TimerCheck($nTime)
    Return _TimerStart() - $nTime
EndFunc

Edit:

Removed unused variable.

Martin: Sorry i didn't reply to you sooner, I was off on another tangent. I can't do it that way when people pause/unpause multiple times.

Smoke: I reread the 5th post and at the time i had discounted it because I saw it returned in days, months, years etc and I was looking for seconds or milliseconds, upon rereading I see that I just have to remove some of your code and I will have it in milliseconds. I'll have to look more into it, but it might work for my purposes. Also I saw your latest reply and I will have to look at it later when I get time and see if that is another option for me. The reason I've been attempting to figure out how to convert timerinit into milliseconds is because i already wrote the code thinking it was in milliseconds. So it would be easy for me to just take that timestamp and say divide it by TimerInit()/TimerDiff(0) or something. Anways I gotta go so I'll look into your latest post when I get back.

Edit: by the way I'll also have to be able to take a date from in a file such as "Mar 03 2008 10:23:45" and be able to convert it into whatever timestamp I end up using. I've already managed to do that with datediff since epoch so I know its doable at least. Anyways really gotta go now. Thanks for all the help.

That only covered 95 through XP it seems, this seems to be more to the point, but I did notice it's off about 6 or 7 ms on my machine due to the time to pass from function to function.

Dim $nTimeStart = _TimerStart()
While 1
    ConsoleWrite(_TimerCheck($nTimeStart) & @CRLF)
    Sleep(100)
WEnd

Func _TimerStart()
    Local $atGT
    If @OSTYPE = "WIN32_WINDOWS" Then
        $atGT = DllCall("Winmm.dll", "dword", "timeGetTime")
    Else
        $atGT = DllCall("Kernel32.dll", "dword", "GetTickCount")
    EndIf
    If IsArray($atGT) Then Return $atGT[0]
    Return 0
EndFunc

Func _TimerCheck($nTime)
    Local $nCurrent = _TimerStart()
    Return $nCurrent - $nTime
EndFunc

Thanks for all the help, I think I got all the stuff i need to scrap timerinit and try using a diff method now. Thanks for all the options to look at.
