Getting time to open of an application

set starttime to time of (current date)

	tell application "Microsoft Word"
		make new document
	end tell

set endtime to  time of (current date)

set CalcTime to endtime - starttime

CalcTime is a number like 1 or 2 but no time (in milliseconds?)
How can I show the time for opening a new document?

You’ll need to use additional software to get milliseconds. Extra Suites offers this feature and much more.

“Jon’s Commands.osax” (free) also has “the ticks” command that returns ticks (I believe 1/60th of a second)–and several other useful commands.
