1614556800000

1614556800000 is a Unix timestamp represented in milliseconds. It measures the amount of time that has elapsed since the standard Unix epoch, defined as 00:00:00 Coordinated Universal Time (UTC) on January 1, 1970. Unlike timestamps in seconds, this figure uses millisecond precision.

UTC date and time: 1614556800000 milliseconds equals 2021-02-28T00:00:00.000Z in ISO 8601 format. In any other time zone, the wall clock time will be offset accordingly (for example, in a time zone one hour ahead, it would be 2021-02-28T01:00:00.000+01:00).

Usage: This form is common in programming environments that work with JavaScript, Java, and many other languages. JavaScript's Date.now() returns the current time in milliseconds since the epoch, and new Date(1614556800000).toISOString() yields 2021-02-28T00:00:00.000Z. Other languages offer equivalent functionality, such as Python's time.time() multiplied by 1000 or Java's System.currentTimeMillis().

Because it uses 13 digits, it can be stored in standard 64-bit integer fields and remains valid for dates far in the future until the 64-bit limit is reached. It is commonly used in logs, databases, and event timestamps to record precise moments with millisecond resolution.
