Can time be measured to milliseconds?

I know you can pause a macro for a certain number of milliseconds using

Public Declare Sub Sleep Lib "kernel32" _
(ByVal dwMilliseconds As Long)
Option Private Module

but I want to know the time between a certain number of iterations. The
code runs too fast per iteration to calculate using seconds, and I can't seem
to figure out how to measure more precisely. My code is as follows:

Function timeRemaining(lastTime, curRow, endRow, cycles)

lastTime = CDbl(lastTime)

Dim timeNow As Double
Dim cyclesLeft As Long
timeNow = CDbl(Time)
cyclesLeft = Int((endRow - curRow) / cycles)

timeRemaining = format(CDate((timeNow - lastTime) * cyclesLeft), "h:mm:ss")

lastTime = CDbl(Time)

End Function

Thanks for your help,

Maybe this is what you want:

Option Explicit
Private lStartTime As Long
Private Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub StartSW()
lStartTime = timeGetTime()
End Sub

Sub StopSW(Optional ByRef strMessage As Variant = "")
MsgBox "Done in " & timeGetTime() - lStartTime & " msecs", , strMessage
End Sub

Sub ForTesting()

Dim i as long

StartSW
For i = 1 to 10000
'testing code
Next
StopSW

End Sub

Yes, that will work well. Thanks very much!
