Adding 480 Milliseconds to a duration

[uteho]

Hallo,
I have a script which gets a certain duration from another source. I have to add 480 Milliseconds to this duration.

This is the relevant part of the script:
set timeValues to time of date durationString

Now I would add the 480 Milliseconds to timeValue. How can I do this?

Probably very easy!

Thanks a lot

Ute

Unfortunately not, in AppleScript the smallest time unit of the class date is seconds
