Notification display time

I have this in a script in Scriptdebugger

display notification time string of (current date) & " Backup starting" with title ("Backup") sound name "Ping"

It displays for 10 secs. Is there anyway to make it display for say 30 secs?

Short answer is no. If you need something longer, use display dialog or display alert with the giving up after parameter.

Thank you Shane, display alert lets me do what I want

I circumvent this problem by “making” my own Notification system combining AppleScript with Ubersicht. With this, text (of any color, fonts…), drawing, tables, picts … basically anything can appear on your desktop for the time you prefer.

An other example here with my calendar appointments (left-bottom of my screen) and my To_Do list (center -bottom).
