- Review the input and the clearly labeled output behavior.

Total milliseconds/seconds, ISO 8601, clock form, and component values.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Months and years are rejected because their exact duration depends on a calendar start date.
