Why 🤔

Because when you manipulate date with javascript Date class it automatically apply the current timezone. Using timestamp is a good way to avoid timezones's influences. But using timestamp for huge maninupulations can be very hard (ex: go to next months).
That why i created timestamp-utils, it's a powerful util package to easly manipulate timestamp.

How to use ✍️

Install timestamp-utils via npm :

npm install --save timestamp-utils

Or via yarn :

yarn add timestamp-utils

Use it :

import t from 'timestamp-utils'

const now = new Date().getTime()
const timestamp = t.addDays(now, 3)

API 📖

decompose(timestamp, timezone='UTC')

Params :

timestamp : Int (timestamp) timezone : String (since v2.0.0)

getWeekDay(timestamp)

Return : Integer
Params :

timestamp : Int (timestamp) timezone : String (since v1.0.3)

Available since : v1.0.3

Return the timestamp's week day (eg: 0 for "monday").

getDay(timestamp)

Return : String
Params :

timestamp : Int (timestamp) timezone : String (since v1.0.3)

Return the timestamp's day (eg: "01" for "monday").

getHours(timestamp)

Return : String
Params :

Return the timestamp's hours.

getMinutes(timestamp)

Return : String
Params :

Return the timestamp's minutes.

getSeconds(timestamp)

Return : String
Params :

timestamp : Int (timestamp) timezone : String (since v1.0.3)

Available since : v1.0.0

Return the timestamp's seconds.

getMilliseconds(timestamp)

Return : String
Params :

Available since : v1.0.0

Return the timestamp's milliseconds.

addYears(timestamp, years)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) years: Int (years to add)

Available since : v1.0.0

Add the given years to the given timestamp. years can be negative to subtract years.

addMonths(timestamp, months)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) months: Int (months to add)

Available since : v1.0.0

Add the given months to the given timestamp. months can be negative to subtract months.

⚠️ Note : addMonths doesn't add same amont of day.
addMonths add days depends on the given day, the result is always the nearest month's day that the given month's day :
09 October + 1 month => 09 November (+31 days) 31 August + 1 month => 30 September (+30 days) 31 January 2018 + 1 month => 28 February (+28 days)

addDays(timestamp, days)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) days: Int (days to add)

Available since : v1.0.0

Add the given days to the given timestamp. days can be negative to subtract days.

addHours(timestamp, hours)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) hours: Int (hours to add)

Available since : v1.0.0

Add the given hours to the given timestamp. hours can be negative to subtract hours.

addMinutes(timestamp, minutes)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) minutes: Int (minutes to add)

Available since : v1.0.0

Add the given minutes to the given timestamp. minutes can be negative to subtract minutes.

addSeconds(timestamp, seconds)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) seconds: Int (seconds to add)

Available since : v1.0.0

Add the given seconds to the given timestamp. seconds can be negative to subtract seconds.

addMilliseconds(timestamp, milliseconds)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) milliseconds: Int (milliseconds to add)

Available since : v1.0.0

Add the given milliseconds to the given timestamp. milliseconds can be negative to subtract milliseconds.

add(timestamp, values)

Return : Int (timestamp)
Params :

timestamp : Int (timestamp) values: Object

Available since : v1.0.0

add is a combo of all previous "add" methods. values is an object that follow this pattern : { years, months, days, hours, minutes, seconds, milliseconds } All values values are int and represent the key value to add.
Example : { years: 3, days: -1, seconds: 20 } will add 3 years, subtract 1 days and add 20 seconds to the given timestamp.

⚠️ Note : add calls addMilliseconds, addSeconds, addMinutes, addHours, addDays, addMonths and addYears in this order.
That mean, according to addMonths's note, add(t, { days: -1, months: -1 }) and addDays(addMonths(t, -1), -1) are not always equals.
Example : add(30 March 2018, { days: -1, months: -1 }) => 28 February 2018, addDays(addMonths(30 March 2018, -1), -1) => 27 February 2018

Changelog 📋
v2.2.0
Update some dependencies #180.
Enable 0 value for set method #125 #181.
Fix timezoneOffset util date parsing #183.
v2.1.0
Adding set methods :
- setYear(timestamp, year) - setMonth(timestamp, month) - setWeekDay(timestamp, weekDay) - setDay(timestamp, day) - setHours(timestamp, hours) - setMinutes(timestamp, minutes) - setSeconds(timestamp, seconds) - setMilliseconds(timestamp, millisecondes) - set(timestamp, values)

v2.0.2

Fix getWeekDay usage of timezone.

v2.0.1

Fix decompose slow execution speed.

v2.0.0

decompose is no longer accessible by using deconstructing import. Now decompose is accessible by doing :

import t from 'timestamp-utils'
const results = t.decompose(now)

decompose now support timezone :

import t from 'timestamp-utils'
const results = t.decompose(now, 'Europe/Paris')

New method setTimezone :

import t from 'timestamp-utils'
t.setTimezone('Europe/Paris')
