英语技术说明
Device clock determines the result. UTC input avoids local daylight-saving ambiguity. No background notification or guarantee while the page is closed.
Uses an absolute deadline and recomputes remaining time from the device clock, so delayed screen refreshes do not accumulate interval drift.
A target one hour from now → approximately 01:00:00 remaining.
