TimerInit() returns different tamp on different systems?

9 posts in this topic

I found that TimerInit() returns different timestamps on different machines. Time is same on both machines 21 aug 2012 20:33.

On 32 bit xp machine I get 17452391718

On 64 bit win 7 (au3 is still 32 bit) I get 94856379079

This difference is huge. Basically I want to add ping command to server - I send ping packet to server and then server sends back the return value of TimerInit() so that I can calculate time difference on client side. Does anyone know what might cause it? Any alternatives to TimerInit() you could suggest?

TimerInit doesn't return a timestamp, so trying to read what it returns is irrelevant. See bug tracker tickets #2025, and #2008 for more of an explanation.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Thanks for info.

Help file said:

Returns a timestamp (in milliseconds).

Which seems to be wrong in this case.

Anything I could use for what I want to do?

Edit: I came up with that:

based on but these are 2 timestamps that are calculated on same second 607893382656 and 541842352128. Just wondering if anything is wrong with algorithm.

Func TimeStamp()
    Local $stSystemTime = DllStructCreate('ushort;ushort;ushort;ushort;ushort;ushort;ushort;ushort')
    DllCall('kernel32.dll', 'none', 'GetSystemTime', 'ptr', DllStructGetPtr($stSystemTime))
    $sMilliSeconds = 1
    For $i = 1 to 8
        $sMilliSeconds *= DllStructGetData($stSystemTime, $i)
    Next
    $stSystemTime = 0
    Return $sMilliSeconds
EndFunc

I figured that following code gives very random numbers.

$time = TimeStamp()
Sleep(200)
MsgBox(0,0,TimeStamp()-$time)
Exit

E1M1,

Be careful deciding that number are "random" - randomness is a very difficult concept and the value you are getting from that code is nowhere near random. The Random function uses a very good alogorithm and is as good as you can get for normal purposes. ;)

Sorry for that. By random I meant that when sleep time is always same TimeStamp()-$time is always different. I am currently trying to figure out how to properly convert this to timestamp

Timestamp's come in many different flavors. And should not really be shared across different systems (unless your sure there of the same flavor ... and there synchronized down to the lowest(at least) used unit.)

For additional information/data on the AutoIt TimeStamp() you might like to take a look at the code in the AutoIt included "Timers.au3" UDF.

TimerInt() should be used with TimerDiff() which is explained here: http://www.autoitscript.com/autoit3/docs/functions/TimerInit.htm

this code will work on any machine:

$Timer = TimerInt()
Sleep(3000)
If TimerDiff($Timer) >= 3000 Then MsgBox(0, "Ding!", "It has been " & Round((TimerDiff($Timer)/1000), 0) & " seconds.")
