ztime

Promise-based timer utilities

Installation

npm install --save ztime

Basic usage

    const ztime = require('ztime');

    ztime("16:00").wait().then(() => console.log('Tea time'));

The goal was to design a no-dependency library to perform simple date-time manipulation and trigger timer events.

Principles:

• All dates and times are UTC!
• ECMAScript Epoch-basd. No leap seconds.
• Date-time objects are immutable.

The date-time specifier is understand a simple mini-language:

deta-time-spec: origin WS+ (('+'|'-') offset)+

origin: '' | 'today' | 'now'
      | (hh:mmm | hh:mm:ss)
      | yyyy-mm-ddThh:mm:ssZ
      | ('sunday'| .. |'saturday')

offset: (hh:mm | hh:mm:ss)
      

When the date is not explicitly specified, events are create in the future. So ztime("monday") is next monday (excl. today).
