[TimPin28]

Summary
Setting the time to the same time as an existing record was able to edit a record and there was no input validation. It even changed the value in the database.

Steps to Reproduce:

1. Go to Sales Tab
2. Hover over on the sales record: "6:00 PM with amount ₱2283.00"
3. Click on that record
4. Edit Time to 5:00 PM
5. Click Save Changes

Expected Results:
Input validation asking for a different input in the time field should appear

Actual Results:
There was no input validation and it changed the time in the database.
