FAQ

Seconds or milliseconds?: A value with more than 10 digits is treated as milliseconds. Shorter values are treated as seconds.
Which timezone is “local”?: The timezone of the browser. UTC is shown separately as an ISO string.
What date format can I type?: Something the browser can parse, such as 2026-10-03T09:00. A bare date is interpreted in local time.
