Question : Convert Integer to time format in SQL Server 2005

I have a file that gets exported from an Excel spreadsheet. The time in the spreadsheet is saved in 24 hour format as a number in Excel (ex: 0900 or 1530). When import SQL simply sees these values as numbers. I need to convert these numbers the standard time format SQL uses so I can store it with a date in a DATE/TIME field. The 0900 would then have a value of 9:00:00 AM and 1530 would have a value of 3:30:00 PM. Thanks.

Answer : Convert Integer to time format in SQL Server 2005

I apologize for the long delay in getting back to this post; I have been gone for a while. With the other solutions I was getting different types of errors; one solution yielded no results. Below is the function I had to end up writing that works . It may be a little complex for the task but, it works all of the time for what I'm looking for. Thanks anyway for your time and effort experts.
