Simple Time (STime)

STime is a simple javascript library used to generate and manipulate date/time. STime is designed to have a simple, readable API that is as pleasing to the eye as it is useful.

Installation

npm install stime

Basic Usage

Using in a script

STime does not require any additional calls or instansiation to use, simply call the STime library after installation:

const stime = require('stime');

Getting the current date/time

The current time returned from any of the generator methods is a Time, more information about how to interact with a time can be found in the Interacting with time section.

const stime = require('stime');
const time = stime.now();

Creating an instance of time in the future or past

A builder is provided to create a date at a particular date/time from the current date/time, this can be accessed in the following way:

const stime = require('stime');
stime.create(7).days().from().now(); // An instance of time 7 days from today

A number of options are available for use with the builder, depending which stage you are at:

Stage	Available options	Example
Creation	days months years hours minutes seconds	stime.create(7).hours()
Units	from before	stime.create(7).days().before()
Direction	now time	stime.create(6).hours().after().now()

Getting the difference between two times

A difference method is available in STime. This method takes two times and will report the difference between those two times.

Example

const stime = require('stime');
const timeOne = stime.fromDate(new Date('01-01-2020 15:00:00'));
const timeTwo = stime.fromDate(new Date('01-05-2020 15:00:00'));
stime.difference(timeOne, timeTwo).getTotalDays(); // 4

Creating a date from a native date

To allow for the greatest level of flexibility, STime offers a mechanism to get a time from a native javascript date.

const stime = require('stime');
stime.fromDate(new Date('01-01-2020 14:00:00')); // A time at the specified date

Interacting with time

Method	Return value
getDay	The current day as an integer
getHours	The current hour as an integer
getMinutes	The current minute as an integer
getSeconds	The current second as an integer
getYear	The current year as an integer
getMonth	The current month as an integer
toTimestamp	Convert the time instance to a unix timestamp
format	Format a time into a particular format

Example

const stime = require('stime');
const time = stime.now();
time.getDay(); // Todays day of the month

Formatting a time
