I have a site that uses several start and end times and also various other times that have to be scheduled. I needed to be able to narrow down the listing with start and end times. I also wanted to be able to specify various time increments in minutes. My last requirement was that I needed to be able to show what time was stored in the database by specifying the SELECTED attribute for the option statement.
This is something I am posting to give back to this site as I have used it over and over to help me in a large project I am finalizing in the next week or so.
