It was released on August 18, 2021, [1] [3] almost 3 years after Windows Server 2019, and a few months before the Windows 11 operating system. Windows Server 2022 is based on the "Iron" codebase. [5] It is similar to Windows 10 21H2, but its updates are incompatible with it. [5] Like its predecessor, Windows Server 2019, it requires x64 processors.
The network time server in Windows 2000 Server (and Windows XP) does not implement NTP disciplined synchronization, only locally disciplined synchronization with NTP/SNTP correction. [44] Beginning with Windows Server 2003 and Windows Vista, the NTP provider for W32Time became compatible with a significant subset of NTPv3. [45]
The 64-bit timestamps used by NTP consist of a 32-bit part for seconds and a 32-bit part for fractional second, giving NTP a time scale that rolls over every 2 32 seconds (136 years) and a theoretical resolution of 2 −32 second (233 picoseconds). NTP uses an epoch of 1 January 1900.
As of MySQL 8.0.28, released in January 2022, the functions FROM_UNIXTIME(), UNIX_TIMESTAMP(), and CONVERT_TZ() handle 64-bit values on platforms that support them. This includes 64-bit versions of Linux, macOS, and Windows. [32] [33] In older versions, built-in functions like UNIX_TIMESTAMP() will return 0 after 03:14:07 UTC on 19 January 2038 ...
The first widely known case of NTP server problems began in May 2003, when Netgear's hardware products flooded the University of Wisconsin–Madison's NTP server with requests. [5] University personnel initially assumed this was a malicious distributed denial of service attack and took actions to block the flood at their network border. Rather ...
The time server may be a local network time server or an internet time server. The most important and widely used protocol for distributing and synchronising time over the Internet is the Network Time Protocol (NTP), though other less-popular or outdated time protocols continue in use. A variety of protocols are in common use for sending time ...

The ntpd program is an operating-system daemon that sets and maintains a computer system's system time in synchronization with Internet-standard time servers.It is a complete implementation of the Network Time Protocol (NTP) version 4, but retains compatibility with versions 1, 2, and 3 as defined by RFC 1059, RFC 1119, and RFC 1305, respectively. ntpd performs most computations in 64-bit ...
