From what I understand that's pretty close to the optimal solution.
The only thing is that the format of the idle time has changed with Mac
OS X 10.3. Prior to 10.3 the value returned is in hexadecimal, with
10.3 it is now a decimal number. So you need to detect the version of
Mac OS X the user is running and treat the data accordingly:
----
display dialog "The user was idle for " & IdleTime() & " seconds"
delay 3
display dialog "The user was idle for " & IdleTime() & " seconds"
on IdleTime()
set ioregResult to do shell script "ioreg -c IOHIDSystem | awk '/Idle/
{x = $5} END {print x}'"
-- Check the version of the OS
set systemVersion to my NumToHex(system attribute "sysv")
if the systemVersion is greater than or equal to "1000" then
-- we are using Mac OS X
if the systemVersion is less than "1030" then
-- we are not using Panther
set secondsIdle to hex2Dec(text from character 2 to -2 of
ioregResult) / 1.0E+9
else
-- we are using Panther
set secondsIdle to (ioregResult as number) / 1.0E+9
end if
end if
return secondsIdle
end IdleTime
-- this function adapted from
-- <
http://www.apple.com/applescript/guidebook/sbrt/pgs/sbrt06.htm>
on NumToHex(hexData)
set hexString to {}
repeat 4 times
set hexString to ((hexData mod 16) as string) & hexString
set hexData to hexData div 16
end repeat
return (hexString as string)
end NumToHex
on hex2Dec(hexNum)
set decNum to 0
set hexDigits to "123456789ABCDEF"
set Nbdigits to (length of hexNum) - 1
repeat with i from 0 to Nbdigits
set lastOne to character (Nbdigits + 1 - i) of hexNum
set decNum to decNum + (offset of lastOne in hexDigits) * (16 ^ i)
end repeat
return decNum
end hex2Dec

I have some script actions I want to occur only if the computer has
