December 13 of this year is the beginning of signed 32-bit Unix time, and is scheduled to end in January 19, 2038.

Summary

Political and military

1901 started with the unification of multiple British colonies in Australia on January 1 to form the Commonwealth of Australia after a referendum in 1900, Subsequently, the 1901 Australian election would see the first Australian prime minister, Edmund Barton. On the same day, Nigeria became a British protectorate.

Following this, the Victorian Era would come to an end after Queen Victoria died on January 22 after a reign of 63 years and 216 days, which was longer than those of any of her predecessors. Her son, Edward VII, succeeded her to the throne.

In the United States, although President William McKinley won reelection in the previous year's presidential election to a second term, he became the third president to be assassinated in office when he was shot by anarchist Leon Czolgosz on September 6, dying eight days later. His vice president, Theodore Roosevelt would succeed him.

Significance of 1901 for software

The date of Friday December 13 20:45:52 1901 is significant for modern computers because it is the earliest date representable with a signed 32-bit integer on systems that reference time in seconds since the Unix epoch. This corresponds to −2147483648 seconds from Thursday January 1 00:00:00 1970. Software that depends on this representation cannot represent an earlier date.

Similarly, many computer systems suffer from the year 2038 problem, when the positive number of seconds since 1970 exceeds 2147483647 (01111111 11111111 11111111 11111111 in binary) and, if represented as a signed 32-bit integer, wraps to −2147483648, representing Friday December 13 20:45:52 1901. In a way, the year 2038 problem for using signed 32-bit integers with January 1, 1970, as the zero date is as the year 2000 problem was for software using two-digit decimal integers with January 1, 1900, as the zero date.
