Depends on the size, the type of heating element, the water temperature and the ambient air temperature. I used to have a 300 gallon hot tub with a big natural gas heater; it took about 3 hours from "stone cold" to "102 degrees". I now have a 200 gallon tub with a small electrical heater; from 40 degrees to 102 degrees now takes about 20 hours.

Depends on what temp the water starts at and how hot you are expecting it to get. It will also depend on how powerful your heating element is for the hot tub. Typically you can expect about 1-2 degrees an hour. Within 24 hours a 500 gallon tub is typically hot! Leave the cover on the tub when heating it up. If you leave the cover off, a lot of heat can escape.

Getting into a hot tub involves heat transfer through conduction and convection.

The time it takes to heat a 450-gallon hot tub depends on several factors, including the heater's BTU rating and the initial and desired water temperature. Generally, a standard electric hot tub heater (around 5.5 kW) can raise the water temperature by about 2-3°F per hour. Therefore, if you want to raise the temperature from 50°F to 100°F, it could take approximately 16-25 hours. For more accurate estimates, consult your hot tub's specifications and heater capacity.
