Repeatedly calls a function or executes a code snippet, with a fixed time delay between each call.
A function to be executed every specified milliseconds. The function should not have any parameters, and no return value is expected.
The time, in milliseconds (thousandths of a second), the timer specifies the delay between executions of the specified function or code. If this parameter is less than 100, a value of 100 is used. Note that the actual delay might be longer.
