Seconds or milliseconds?
10 digits is usually seconds (1767225600); 13 digits is milliseconds (1767225600000), used by JavaScript and many APIs. The Unix Timestamp Converter detects both automatically.
Convert in code
JavaScript: new Date(1767225600 * 1000).toISOString(). Python: datetime.fromtimestamp(1767225600, tz=timezone.utc). SQL (MySQL): FROM_UNIXTIME(1767225600). Excel: =(A1/86400)+DATE(1970,1,1) then format as date.
Time zones
A timestamp is always UTC. Convert it to local time only when displaying it – store and compare in UTC.
The 2038 problem
32-bit signed timestamps overflow on 19 January 2038. Modern 64-bit systems are fine, but old embedded devices and databases may not be.
Frequently asked questions
