A CLI program that prints the local or utc week and time in the ISO 8601 format, e.g. 2006-W52-7T10:26:20.485371700.

Tom Scott's Why It's Already 2020 inspired me to write this. This is not designed to print the full ISO 8601 date and time, only the week date. For more technical information on ISO week, visit Wikipedia.

Crates.io Differneces

  • Crates.io installations will return --dirty suffix at the end of their version. This is harmless bug and does not impact the stability ISOW.

  • Self-updater is unsupported in the Crates.io releases. As of 0.3.14, this will return a "feature is unsupported" message.
