What these items mean
The values and formats used by this tool have a practical meaning beyond the result. This short guide explains what they are, what they are used for, and where they came from.
Unix Timestamp
A Unix timestamp is a count of elapsed seconds from 00:00:00 UTC on 1 January 1970, commonly called the Unix epoch. Some systems also use milliseconds. It is used to store, compare, sort, and exchange dates as a simple number without storing a formatted time-zone string.
The convention grew out of Unix operating systems at Bell Labs in the early 1970s. Ken Thompson and Dennis Ritchie were central creators of Unix, while the timestamp behavior was later documented and standardized through POSIX rather than being attributed to one individual inventor.
Dates, times, and time zones
A date identifies a calendar day, a time identifies a position within that day, and a time zone describes the local offset and rules used to display it. These values are used for schedules, logs, deadlines, reports, and conversions between human-readable dates and machine values.
Modern computer timekeeping developed from astronomical and civil standards. UTC is maintained internationally, while the IANA Time Zone Database records regional changes such as daylight-saving rules; there is no single creator of the whole system.
Authoritative resources
For date and time context, refer to the IANA Time Zone Database and IETF RFC 3339.
