Examples

Small apps you can run and edit right here. Each one shows one thing the library does, with a few things to try in the preview.

Zones

A meeting across zones
One moment, read in six cities. The meeting is set where you are, and in() shows it everywhere else.
Try Set the time to 23:00. Tokyo and Kolkata move to the next day, and say so.

Lengths of time

Countdown to a launch
The time left until Friday at 5 PM, as a duration you can print three ways. until() does the subtraction and keeps the units.
Try Watch the seconds. Each tick asks now().until(launch) again and prints what comes back.
Typed durations
A field that reads lengths of time the way people type them. duration() takes 1h 30m, 90 minutes or 2 weeks and 3 days, and says what’s wrong with anything else.
Try Type 90 minutes. It reads as 1 hour, 30 minutes, and 1.5 hours in total.
