I don't know the status today on clocks in pc's but you must realize that
clocks in pc's are pretty lousy.
>From what I last recalled, pc clocks are only accurate to 1/3 of a second.
And pc clocks do tend to run back or forward.
You can minimize this by dooing a NET SET TIME in the logon scipt of a
windows network, thus setting pc clocks just every logon.
You can use a atomic clock program on the server with internet access.
If you really need millisecond accuracy, you will need to buy you a hardware
atomic clock (radio based) to put in your or all computers.
Depends on how accurate it must be.

You pasted the code into a module instead of a class? Or you saved the
class code to a name other than clsTimer.

That looks real good. The time kind of got away from me so if I don't get a
reply right away I can go with what I've got. But this would be better.
I'm getting a compile error on
Dim mclsTimer As clsTimer
User defined type not defined.
What have I left out?
Best,
Rocky

Rocky,
Below is a modification to the TestTimer to time your form opening / closing
10 times. Obviously replace the form name(s) with your own.
Option Compare Database
Option Explicit
Dim mclsTimer As clsTimer
Function TestTimer()
Dim intLoopCnt As Integer
Set mclsTimer = New clsTimer
For intLoopCnt = 1 To 10
DoCmd.OpenForm "frm_MoviesTab"
DoCmd.Close acForm, "frm_MoviesTab"
Next intLoopCnt
MsgBox mclsTimer.EndTimer & " ms elapsed time - Hit any key to
continue", , "TIMER TEST 1"
mclsTimer.StartTimer
For intLoopCnt = 1 To 10
DoCmd.OpenForm "frm_MoviesTab"
DoCmd.Close acForm, "frm_MoviesTab"
Next intLoopCnt
MsgBox mclsTimer.EndTimer & " ms elapsed time - Hit any key to
continue", , "TIMER TEST 1"
Set mclsTimer = Nothing
End Function

John:
Will it work across forms?
I'm demonstrating your Just-In-Time forms at the AUGSD tonight and since
it's a single user box the difference in opening time is hard to see, even
though it's a factor of 2-4.
I think I need to start my timing from the Main Menu Click event that opens
the form with the sub-forms in it, as some of the processing of loading the
sub-form's recordsets goes on even before the called form's OnOpen event.
Best,
Rocky

Rocky,
Here is the class I use for timing things such as the opening of forms and
such, with a timer test function you can place in a module to play around
with the class. Dead simple to use.
The nice thing about using a class is that you can have as many instances as
you need timing various stuff since the variable tracking elapsed time is
private to the class instance.

Option Explicit
Dim mclsTimer As clsTimer
Function TestTimer()
Set mclsTimer = New clsTimer
MsgBox "Hit any key to continue", , "TIMER TEST 1"
MsgBox mclsTimer.EndTimer & " ms elapsed time - Hit any key to
continue", , "TIMER TEST 1"
MsgBox mclsTimer.EndTimer & " ms total elapsed time - Hit any key to
continue", , "TIMER TEST 2"
mclsTimer.StartTimer
MsgBox "Hit any key to continue", , "TIMER TEST 3"
MsgBox mclsTimer.EndTimer() & " ms elapsed time", , "TIMER TEST3"
Set mclsTimer = Nothing
End Function

Dear List:
Is it possible to access/store/display the time in increments smaller than
seconds. I need to time something in fractions of a second.
