This is basically just a Number Spinner script. You can use it in any number spinning function such as times, dates and of course, plain numbers. For dates, though, you need to modify the script to dynamically set the range of day depending on the entered month and year (maybe that's for the next version).
See samples below:
Time-in (h:mm) ^V (Military time format. Choose first which field you want to spin)
Number of days: ^V (Default value of 5, ranges from 0-50 with increment of 0.5, has leading zero, and has 2 decimal places)
Since the script is object-oriented, it is easy to create multiple instances of the spinner object and set different characteristics for each one.
Oh, and did I mention it doesn't use images? :)
