(c)Bumblehead

npm version Build Status

simpletime manages dates and renders them to unicode formats. (i18n through worldtime).

  • formats and extracts dates with unicode forms
  • uses YMDArr objects to simplify time manipulation
  • does not depend on a library
simpletime.extractDateFormatted(
  'April 5, 2013 9:23:41 pm 420',
  'MMMM d, y h:mm:ss a z'
);
// Fri Apr 05 2013 21:23:41 GMT-0700 (PDT)

simpletime.applyFormatDate(
  new Date('Fri Apr 05 2013 21:23:41 GMT-0700 (PDT)'),
  'MMMM d, y h:mm:ss a z'
);
// 'April 5, 2013 9:23:41 pm 420'

simpletime.getElapsedTimeObj(
  new Date('Sun Apr 07 2013 18:08:45 GMT-0700 (PDT)'),
  new Date('Sun Apr 07 2013 23:59:59 GMT-0700 (PDT)')
);
// { ms: 0, sec: 14, min: 51, hour: 5, day: 0 }
