That depends on what exactly you want that clock to do. For example simple counting in seconds will be much easier than implementing date, leap years etc.

In the simplest you just need to divide the 32768hz clock to get 1 pulse per second, and use that pulse to increment the counter. You will also need some way to set the counter value and also read it.
