- iso date
- This module was built for the exact needs of parsing ISO dates to the microformats standard.
-
- * Parses and builds ISO dates to the W3C note, HTML5 or RFC3339 profiles.
- * Also allows for profile detection using 'auto'
- * Outputs to the same level of specificity of date and time that was input
