Typescript named type aliases to clarify the meaning of the variable

It's not always clear what does number or string type mean.

Let's imagine you are describing setTimeout

declare function setTimeout(handler: TimerHandler, timeout?: number, ...arguments: any[]): number;

In't not clear what number to pass in timeout. Let's refactor it

type Milliseconds = number;
declare function setTimeout(handler: TimerHandler, timeout?: Milliseconds, ...arguments: any[]): number;

Now it's much more clear, and user will see hints when typing this function in IDE.

So this library is just a set of such aliases. For now it contains

export type Milliseconds = number;
export type Seconds = number;
export type Minutes = number;
export type Hours = number;
export type Days = number;
export type Months = number;
export type Years = number;
export type Centuries = number;

So use it to clarify your inputs!
