Timer
  How can I do this:
1. Create timer (state: 0ms)
2. (do some operations)
3. Get elapsed time since timer start (state e.g.: 1050ms)
4. Kill timer

Could you use some API call (I don't know what OS you're using) to get the current time, store it in a var, then when you want to compare, get the (new) current time, and subtract?

RobGrant, I know that I can use API calls but
-kernel32::GetLocalTime returns always zero in milliseconds variable
-I found only user32::SetTimer and user32::KillTimer and no command for get state

Hello

MSDN information

GetTickCount

The GetTickCount function retrieves the number of milliseconds that have elapsed since the system was started. It is limited to the resolution of the system timer. To obtain the system timer resolution, use the GetSystemTimeAdjustment function.

DWORD GetTickCount(void);

Nsis solution

Section "timer" timer

System::Alloc 400

pop$2

System::Call 'kernel32::GetTickCount()i .r0'

>System::Free $2

MessageBox MB_OK "Inicial Time  $0 in ms"


>System::Alloc 400

pop$2

System::Call 'kernel32::GetTickCount()i .r1'

>System::Free $2

IntOp$1 $1 - $0

MessageBox MB_OK "Time before start  $1 in ms"


>SectionEnd

This is exactly what I want. Thanks, kike_velez!

Ah cool, this is something that we've always needed and hopefully it actually works (the old solutions on the archive, including mine didn't work very well).
