How can time duration be accurately represented in TypeScript?

As I work on designing an interface for my personal project, I am in need of adding a field that represents the length of time taken to complete a task. What data type and format should I use in TypeScript to express this?

Below is the interface I have created:

export interface Task {
    id: number, 
    name: string,
    taskDate: Date,
    taskDuration: {DURATION TYPE HERE}
}

While there are methods available online to calculate duration based on two dates using taskStart and taskEnd, I am seeking a more straightforward way to input the duration without needing to perform calculations.

Answer №1

ISO 8601 outlines a standardized format for representing durations, which has become widely adopted in various industries.

Here are a few examples:

P1D - representing one day
PT5H - indicating 5 hours
P2YT2S - denoting 2 years and 2 seconds

To learn more about ISO 8601 durations, check out this link: https://en.wikipedia.org/wiki/ISO_8601#Durations
