timeInterpreter

Parse a human readable time string into a canonical format:

date     -> ISO8601: 2020-11-11T00:00:00+00:00, 2020-11-11T00:00:00Z,
datetime -> ISO8601: 2020-11-11T09:36:27+00:00, 2020-11-11T09:36:27Z,
time     -> HH:mm:ssZ,
duration -> milliseconds
timezone -> time offset - +00:00

Usage

const timeInterpreter = require("@onereach/time-interpreter");
const converter = new timeInterpreter();

Parse date

// will be deprecated
converter.formatDatetime(
  "date string",
  false /*ignore time*/,
  "input timezone",
  "output timezone"
); // optional: set timezones by name or time offset, default `Z`
// Input timezone is a default (assumed) timezone and it will be applied if the input date/time doesn't include timezone data

Since v1.0.21:

converter.getISODatetime({

// Invalid value 1.0.8+

Parse time

If the time zone name is used to indicate the input timezone, and this zone has winter and summer time, then the time offset for the input time value is determined to rely on the current date.

converter.formatTime("time string", "input timezone"); // optional: set timezones by name or time offset, default `Z`

let time = converter.formatTime("12:30:10 am", "Europe/Kiev");

    } */

Parse duration

let duration = converter.formatDuration("10.2019"); // number of days in October
// 2678400000

converter.formatDuration("2w 1d5h"); // 1314000000

Define value type and parse

If you don't know what type of an input value: date, date/time or time, you can use converter.parse(value, input timezone, output timezone, input year, input date). Input year (YYYY) is a default year and it will be applied if the input date/time doesn't include year. Input date (in format YYYY-MM-DD) will be applied if the input value type of time. Default year - current year, default date - null, default input timezone - GMT+0.

if input date is not indicated and the defined type of value is time, then the output timezone is ignored. If the defined type of value is date, then the time is set to 00:00:00 in input timezone (default GMT+0).

If the time zone name is used to indicate the input timezone, and this zone has winter and summer time, and if value is time, then the time offset is determined to rely on the current date (unless otherwise specified).

Method tries to defind first if the value is a date. If input value is a sequence of numbers (for example, 234567 or "6453673") it will be parsed as unix time in seconds. If the value looks like these: "12-30-00", "20 45 50", "16.50.00", - the method will try to parse it as a date (MM-DD-YY, YY-MM-DD etc.) and if it's invalid date the value will be parsed as a time (hh mm ss). Values where separator is "/" are parsed only as a date. Values where separator is ":" are parsed only as a time.

// Sinse v1.0.21

  value: "time/date/datetime",

  outputTimezone: "output zone",
