Unix time is held as 32-bit integer Quoting from Wikimedia: The 32-bit representation of Unix time will end after the completion of 2,147,483,647 (2^31 - 1) seconds from the beginning (00:00:00 1 January 1970), i.e., on 19 January, 2038 03:14:08 GMT.

Many Linux systems store Unix time dates as a signed 32-bit integer. 2020-02-13 32-Bit UNIX timestamp rollover sys_gettimeofday () is one of the most used system calls on a generic Linux system and returns the current time in form of an UNIX timestamp (time_t data type) plus fraction (suseconds_t data type). uint32 timevalIntervalTo65536 (timeval &t) Convert a time interval, expressed as a timeval, into a 32-bit time interval expressed in units of 1/65536 seconds. Parameters: t Timeval interval. Returns: 32-bit value corresponding to the given timeval interval. I need to support 64-bit times on a 32-bit ARM embedded Linux system based on kernel version 4.1. I use clock_gettime() and clock_settime() to get/set the time, but they are limited to 32-bit seconds values currently, which results in a year-2038 problem, which is an issue for this system.

If you want full userspace support you must be on Linux 5.6 or higher along with musl 1.2+ or glibc 2.32+. This Unix time is stored in a structure which is 32 bit. Using a 32 bit structure, time can be provided for a defined period beyond which the number cannot be stored in a 32 bit structure and hence will start overflowing. This period is identified as to be falling on 19 January 2038. uint32 timevalIntervalTo65536 (timeval &t) Convert a time interval, expressed as a timeval, into a 32-bit time interval expressed in units of 1/65536 seconds. Parameters: t Timeval interval.

21 Apr 2020 Note: A Unix like operating system frequently stores time as a 32-bit count of seconds. And on the other hand, the Unix() method here returns a 

Before this moment millions of applications will need to either adopt a new convention for time stamps or be migrated to 64-bit systems which will buy the time stamp a "bit" more time. Originally, UNIX was built on a 16-bit CPU, and used a signed 32-bit field for time, the number of seconds since “the epoch” - midnight, Jan 1, 1970.

Using the function on a date beyond this will result in NULL being returned.

During the 1980s, this was the predominant C data model available for 32-bit UNIX platforms. UNIX time is the number of seconds since the 1st of January 1970, which is known as the "epoch". 32-bit variables can hold numbers as big as 2 147 483 647. However, running my long-ago test code does show the time wraps back to the UNIX Epoch. So not all is well with the 32-bit code from the past.

What happens on January 19, 2038? On this date the Unix Time Stamp will cease to work due to a 32-bit overflow. Before this moment millions of applications will need to either adopt a new convention for time stamps or be migrated to 64-bit systems which will buy the time stamp a "bit" more time.

Before this moment millions of applications will need to either adopt a new convention for time stamps or be migrated to 64-bit systems which will buy the time stamp a "bit" more time. Unix Time is stored as a 32-bit signed integer value. As every second ticks away, the value keeps increasing, and it will eventually reach its limitation on 03:14:07, 19 January 2038 as the 32-bit signed integer value will overflow and reset itself to December 13, 1901.
