Unix タイムスタンプ コンバータ

What is the UNIX time stamp?

The Unix time is the number of seconds since January 1st, 1970 00:00:00 UTC. It is a system used to represent time. This point in time does not change regardless of your location. Computer systems can use this to track and sort dated information in dynamic and distributed applications.

Limitations

• A 32-bit overflow will cause the Unix Time Stamp to cease working on January 19th, 2038. Before this moment, millions of applications will need to either adopt a new convention for time stamps or migrate to 64-bit systems, which will buy the time stamp some extra time.
• Any timestamp before 1970 is represented by a negative number, which represents the number of seconds until January 1st, 1970 00:00:00 UTC.
• In Unix time, leap seconds have the same Unix time as the second before it, because each day consists of exactly 86,400 seconds. Therefore, Unix time does not accurately represent UTC.
