1636316919

1636316919 is a Unix timestamp, which represents the number of seconds elapsed since 00:00:00 UTC on 1 January 1970, not counting leap seconds. This particular value corresponds to 2021-11-07T20:28:39Z in ISO 8601 format.

In practical terms, this instant is a point in time used by computers for timekeeping, logging, and time-based computations. It is commonly stored as an integer and can be converted to human-readable dates in various time zones. The 10-digit decimal form is standard for many systems, and the value falls well within the 32-bit signed time_t range on platforms that use 32-bit integers for time, avoiding the immediate concerns of the Year 2038 problem for this timestamp.

Applications that rely on Unix timestamps include file metadata (modification times), database records, event streams, and network protocols where a precise, sortable, and language-agnostic time representation is advantageous. Conversions to other representations—such as RFC 3339 or local time—are routine in programming languages and utilities.

There is no widely known historical event that is uniquely tied to this exact second; it is primarily notable as a data point within the broader system of Unix time used across computing environments.
