Schedule uses America/New_York (IANA), including daylight saving time. Ambiguous fall-back times use the earlier occurrence; nonexistent spring-forward times are invalid. Dates default expired. Manually match these controls to Weekly Flash Sale if needed; there is no automatic sync or recurrence. Sticky fixed positioning can be limited by the surrounding section or ancestor overflow. The configured top offset is combined with the measured sticky header bottom.
