If you are opening this form from another, you could save the time when you
issue the OpenForm, then save the time in the Current event of the
just-opened form. If you want a finer "granularity", someone can probably
tell you how to get time using an API down to the millisecond.
I remember back when the "big deal" of a release was "lightweight forms"
(those with no class module) and how much time they saved. The tech editor
of Access Advisor magagine did a test and found the "significant difference"
claimed turned out to be only 15 milliseconds difference between a
lightweight form and the same form loaded down with all the code you could
stuff in its module.
From that memory, I'm guessing that time to load a form (which, by
definition, is intended to be viewed by a user) is unlikely to make any
significant difference in the users' perception of response... though if you
load it down with images, you might prove otherwise.
