Fix time slider on appointment details from new ticket page.
The minimum ticket length on this screen is .5 hours. The minimum needs to be 0.25 hours.
If I drag it to 0.5 hours and then create ticket and go to linked appointment information it is now 0.25 hours. I can't be doubting the time length with the limitations and differing results.

Also, allow custom times. I have found that if you book a client at 2:30 they will be there between 2:30 or 3.
If you book them at 2:35, they are almost always right on time. Allow duration of 25 minutes and 50 minutes, etc.
