South Africa signed up to use ISO 8601 for date and time representation through national standard ARP 010:1989 in 1998 A.D. The most recent South African Bureau of Standards standard SANS 8601:2009 [1] "... is the identical implementation of ISO 8601:2004, and is adopted with the permission of the International Organization for Standardization" and was reviewed in 2016.
The first RSA-512 factorization in 1999 used hundreds of computers and required the equivalent of 8,400 MIPS years, over an elapsed time of about seven months. [29] By 2009, Benjamin Moody could factor an 512-bit RSA key in 73 days using only public software (GGNFS) and his desktop computer (a dual-core Athlon64 with a 1,900 MHz CPU).
At Independence of Namibia the country inherited the time regulations of South Africa and was in time zone UTC+02:00 all year round. Triggered by fears for school children walking to school before sunrise, Namibian Standard Time, a type of winter time, was introduced in 1993. [7]

In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Every logical operation in a computer takes time to execute, and the time can differ based on the input; with precise measurements of the time for each operation ...
