Like others here I'd need a bit more to convince me to remove my table or use this as an alternative. Like most, I also us the time table to build a time dimension and provide multiple hierarchies to users 12 hour view, 24 hour view, short time descriptions long time descriptions ect without further work on coding in descriptions this wouldn't meet all my needs. This seems like a good option for using in a data retrieval query if you dont already have a time table and your resultset was small to medium, but as a replacement, not for me.
