This worked for me:
set my_date to date string of (get current date)
set my_hours to hours of (get current date)
set my_minutes to minutes of (get current date)
set folder_name to my_date & "_" & my_hours & "h" & my_minutes
tell application "Finder"
activate
make new folder at folder "Customer" of folder "untitled folder" of folder "Desktop" of folder "marjutpoillucci" of folder "Users" of startup disk with properties {name:folder_name}
end tell
