* fix: use hidden input for UTC date value in add-game form The onSubmit handler was setting the datetime-local input's value to an ISO UTC string (e.g. "2026-03-11T17:00:00.000Z"). datetime-local inputs only accept the format "YYYY-MM-DDTHH:MM" — values with a 'Z' timezone suffix are invalid and the browser silently clears the field to "". This caused the form to submit an empty scheduledAt, which the server treated as null, so games were always saved without a date. Fix by keeping the datetime-local input for user interaction (renamed scheduledAtLocal, not submitted) and writing the converted UTC ISO string into a separate hidden input named scheduledAt in the onSubmit handler. Also adds app/lib/date-utils.ts with a localDateTimeToUtcIso helper and matching tests to document and verify the datetime-local ↔ ISO conversion behaviour. https://claude.ai/code/session_0148fgZiXpyvGX8ZX3BFRGCs * refactor: use localDateTimeToUtcIso in component and clean up tests - Import and call localDateTimeToUtcIso in the add-game onSubmit handler instead of duplicating the conversion inline; also applies the null/ invalid-date safety from the utility to the component - Remove the redundant "incompatible with datetime-local" test case (its intent is better expressed as a code comment than a test assertion) - Move the datetime-local incompatibility explanation into a NOTE comment on the utility function's JSDoc https://claude.ai/code/session_0148fgZiXpyvGX8ZX3BFRGCs --------- Co-authored-by: Claude <noreply@anthropic.com>

/**
|
|
* Converts a datetime-local input value (local time, no timezone info)
|
|
* to a UTC ISO string for server submission.
|
|
*
|
|
* `datetime-local` inputs use the format "YYYY-MM-DDTHH:MM" and do NOT accept
|
|
* ISO strings with a timezone designator (e.g. "2026-03-11T17:00:00.000Z").
|
|
* Setting an ISO UTC string directly on a datetime-local input causes the browser
|
|
* to silently clear the field value. Use this function with a separate hidden input
|
|
* to hold the converted UTC value before form submission.
|
|
*
|
|
* Returns null when value is empty, nullish, or not a valid date.
|
|
*
|
|
* NOTE: The returned ISO string (e.g. "2026-03-11T17:00:00.000Z") is intentionally
|
|
* incompatible with datetime-local inputs, which only accept "YYYY-MM-DDTHH:MM".
|
|
* Setting a Z-suffixed string on a datetime-local input causes browsers to silently
|
|
* clear the field. Always write the result to a separate hidden input, not back to
|
|
* the datetime-local input itself.
