When Does A Programmable Thermostat Turn On?

If i set my thermostat to heat my house to 70 at 6 AM, does it kick on at say 545 to bring up the temp, or just kick on at 6 and run until it reaches 70? I know there are thermostats that work that way, but I am not sure if thats the default, or if it just depends on the model.
