I have the common problem of system/document formats for date/time being different on the machine I develop the files on to the machine that I install the files on for the clients. I know that I can use a startup script that includes the line:

Set Use System Formats (On)

But is there any way to actually change the document to use the system format permenantly, instead of every single time the document is opened?

It seems a bit ridiculous to have to do this every time the file is opened!

Create clone of FM file on machine with different date system.

That should do the trick.

Then import all records.

HTH

Well, that would help in some situations, but it doesn't help to create a truly portable file, and neither does it help if a client changes their system settings. I want to be able to develop updates on my machine and deploy them to the clients' machines without having to clone things along the way. I've also tried using a startup script to set to system formats and that does not even get invoked during an AppleScript call to any of the other scripts.

Surely it would be sensible for a file to have a preference to "Always use system settings" (even if those settings change).
