Time is effectively meaningless without the date part. You say you want 
to validate times like 7 pm to 9 pm. Does that mean 7-9 pm standard time 
or daylight time? Without the date you can't know. The time can be 
stored in UTC, but in order to display the time in a format your users 
will understand (local time) you again must know the date.

Even in your example you are specifying the date with the time. So if 
your customer makes a reservation between 7-9pm on May 5th, store a 
datetime range where start_time = May 5, 2010 7:00 PM EDT and end_time = 
May 5, 2010 9:00 PM EDT.
