Timestamp Converter

The ability of the Timestamp Converter to convey a continuous measure of time across different time zones makes it valuable for software developers and computer scientists. The Unix Epoch provides a standard for coordinating and reducing ambiguity between time zones, which is especially useful given the complexity of accurately accounting for global time zones.

What Is Unix Time?

In Unix, time is measured in seconds since midnight of January 1, 1970. (the Unix epoch, or the time when Unix was created). Dates and times in Unix are often stored as a signed 32-bit integer on Linux-based computers. 

Leap Seconds and Unix Time

Whenever a leap second occurs, Unix timestamps might become ambiguous, which presents a challenge. Because of variations in the Earth's rotation and other causes, UTC time is sometimes adjusted by one second. When this occurs, a second must be added to the midnight portion of the Unix timestamp to reflect the leap second. These leap seconds are notoriously difficult to forecast and are typically revealed months in advance.

The Unix Time Stamp Conversion Utility

Since the Unix timestamp is based on the second, we can do some simple conversions so that humans can more easily understand it:

  • 1 Minute: 60 seconds
  • 1 Hour: 3,600 seconds
  • 1 Day: 86,400 seconds
  • 1 Week: 604,800 seconds
  • 1 Month: 2,629,743 seconds
  • 1 Year: 31,556,926 seconds

Each month has an average to make up for the varying number of days. Just like the calendar year, the Unix year is a quarter of a day longer to allow for the addition of a leap day once every four years.
