David Morgan 1d3fbbed7c Revert "Fix duration.toString() to conform the description"
This reverts commit 038e981f89.

Reason for revert: Breaks some tests; visible changes to some web UIs.

Original change's description:
> Fix duration.toString() to conform the description
> 
> Duration.toString() should return in a format of "HH:MM:SS.mmmmmm".
> But when `hours` is less than 10, toString() doesn't have the leading
> zero, which is "H:MM:SS.mmmmmm".
> 
> The corresponding co19 issue: https://github.com/dart-lang/co19/issues/733

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
