Unix Timestamp Converter
Convert Unix time (s, ms, µs, ns), Windows FILETIME, Active Directory lastLogonTimestamp and .NET ticks to dates in any time zone, and back.
Computers store time as a count from a fixed starting point. Unix and most web APIs count seconds (or milliseconds in JavaScript) since 1 January 1970 UTC. Windows and Active Directory count 100-nanosecond intervals since 1601: that's the 18-digit number in lastLogonTimestamp, pwdLastSet and accountExpires. .NET counts the same intervals since year 1. Paste any of them, or a date, to see it in every format and in any time zone.
