How can I create, if possible, Key sort order in Microsoft Excel sheet.

I need time within date in repetitive order: since 08:00 am until 20:00 pm, something like a calendar.

For example, within 23rd September: 08:00 AM, 09:00 AM,...20:00 PM, and than again within same date: 08:00 AM,09:00 AM,...20:00 PM.
