-Don't worry if you didn't understand calculations there. They looks frighteningly at first. Soon, step by step we will learn these things. So, we just saw initialization of `jffies` based clock sources and also we know that the Linux kernel has the global variable `jiffies` that holds the number of ticks that have occured since the kernel started to work. Now, let's look how to use it. To use `jiffies` we just can use `jiffies` global variable by its name or with the call of the `get_jiffies_64` function. This function defined in the [kernel/time/jiffies.c](https://github.com/torvalds/linux/blob/master/kernel/time/jiffies.c) source code file and just returns full full `64-bit` value of the `jiffies`:
