Execute every x seconds, longer than 100s

I have an AppleScript that returns the next meeting on my Outlook calendar and displays information about that meeting to the TB. Sometimes that script seems to make Outlook unresponsive for 1-5 seconds. I'd like to be able to set a period longer than 100 seconds for the script to run; ideally measured in minutes. Is there a reason for the 100s maximum?

You can enter any value (in seconds) as long as it's lower than 2147483647

Wow - thank you! I totally missed that ability in the UX.
