How does epoch time work

Another option is to represent timestamps using the number of milliseconds since the Unix epoch instead of the number of seconds.

Because Linux and all Unix-lookalike operating systems share the same issue, the year issue has been taken seriously for some time, with fixes being added to the kernel since This is ongoing with fixes being added to the kernel as recently as Jan. Of course, a working Linux computer contains a lot more than a kernel.

All of the operating utilities and userland applications that make use of system time through the various APIs and interfaces need to be modified to expect bit values.

File systems too must be updated to accept bit timestamps for files and directories. Linux is everywhere. A catastrophic failure in Linux would mean failures in all sorts of computer-based systems. Linux runs most of the web, most of the public cloud, and even spacecraft. It runs smart homes and self-driving cars. Smartphones have a Unix-derived kernel at their heart.

Practically anything—like network firewalls, routers, and broadband modems—that has embedded operating systems inside run on Linux. But what are the chances that all of those devices will be patched and updated?

But devices like that should be a tiny minority. The vast majority of systems will see the crunch time come and go without incident. At least, until the year approaches, bringing with it the exact same problem for systems that use bit based integers to count the time since the epoch. We can use the date command to verify Linux and other Unix derivatives still use the original, simple scheme of storing the time value as the number of seconds since the epoch.

Using the date command without any parameters prints the current date and time to the terminal window. To see the underlying integer value, we can use a display format string.

We can show that the integer value really represents the time by displaying the number of seconds, sleeping for 10 seconds, and showing the new number of seconds. The two integer values will be different by exactly If we do just that using zero seconds as input our value, date ought to print the date and time of the Unix epoch. Simple is often best. Counting seconds from a fixed datum is the simplest way to mark the passage of time.

But the passage of time brings new challenges. Browse All iPhone Articles Browse All Mac Articles Do I need one? Browse All Android Articles Browse All Smart Home Articles Customize the Taskbar in Windows Browse All Microsoft Office Articles What Is svchost.
