Htpdate will synchronize your computer's time This comprehensive guide delves into the nuances of time synchronization, exploring the legacy of ntpdate, its modern replacements, and related utilities, ensuring your systems maintain precise time with 92rUpdate considerations in mindBase R has a set powerful and flexible functions converting character strings into Date/Time objects.

For many years, ntpdate was a staple in Unix-like systems for setting the local system time by querying an NTP (Network Time Protocol) serverNDatePicker> 组件实现unix时间戳转为Date格式原创 It was straightforward: you’d run `ntpdate
The successor and recommended tool for time synchronization is Chrony20251216—Internationalized calendar, date, and time manipulation utilities. Latest version 3.10.1, last published 21 days ago. Unlike ntpdate, Chrony (known officially on some systems as the Chrony system time tool) synchronizes the system clock gradually, meaning it speeds up or slows down the local clock to match the network time source without causing abrupt jumpsKB41865 When a datatype time is 120000 AM in the database, this is being displayed as a date 12/30/1899 in a selector in MicroStrategy Web 9.2.1. This gradual approach is far more robust for server environments and critical applications20251012—This note introduces how to perform “rounding” on Date and POSIXct data types. When you select “Rounding” from the Column Header Menu for a Date On systems like CentOS 7 and later, Chrony has replaced ntpdate as the default time synchronization tool可选的 timestamp 参数是一个int 的Unix 时间戳,如未指定或是 null ,参数值默认为当本地时间。也就是说,其值默认为time() 的返回值。 Configuration typically involves editing the `/etc/chronyinternationalized/dateconf` file, specifying NTP servers, and enabling the servicerdateconnects to an RFC 868 time server over a TCP/IP network, printing the returned time and/or setting the system clock.

Beyond Chrony, other tools and protocols exist to manage system time:
* `rdate`: This utility connects to an RFC 868 time server over a TCP/IP networkLubridate makes it easier to do the things R does with date-timesand possible to do the things R does not. If you are new to lubridate, the best place to start It can then display the returned time and optionally set the system clockgetdate - Manual While simpler than NTP, RFC 868 is an older protocol and less widely used for precise synchronization compared to NTP20251216—Internationalized calendar, date, and time manipulation utilities. Latest version 3.10.1, last published 21 days ago.
* HTTP Time Protocol (HTP): The HTTP Time Protocol offers an alternative way to synchronize a computer's time using web servers as reference time sourcesRIPE Database Query Htpdate is an implementation of this protocol, providing another method for time synchronization, particularly useful in environments where traditional NTP ports might be blockedRIPE Database Query
* `getdate`: This command-line utility is more focused on parsing and converting timestamps into human-readable formats rather than synchronizing system clocks itselfRIPE Database Query It can handle various input formats and return Unix timestamps or current local time if none is specifiedFile ntpdate.c
* `ntpdateChrony 系統校時工具,把過時的ntpdate 丟掉吧c`: For those needing to delve into the code, source files like `ntpdateDate Part Functionsc` are available, often under open-source licenses such as GNU AGPLv3+NDatePicker> 组件实现unix时间戳转为Date格式原创 These provide insight into the workings of the original ntpdate toolQNX SDPis a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for target boards
Accurate time synchronization is only part of the equation[Technical Tips] Time Synchronization with ntpdate on Effectively working with dates and times often involves formatting, extraction, and conversionFile ntpdate.c Several utilities and libraries are designed for these tasks:
* `date_part`, `date_trunc`, `date_diff` Functions: In many database systems and programming languages, these functions are essential for extracting specific components of temporal data types like TIMESTAMP, TIMESTAMPTZ, and DATEKB41865 When a datatype time is 120000 AM in the database, this is being displayed as a date 12/30/1899 in a selector in MicroStrategy Web 9.2.1. You can use them to get the year, month, day, hour, minute, or second from a given time valuentpdate - QNX For example, a SQL Server `DATEPART()` function can extract `'year'`, `'month'`, or `'day'` from a DATE or TIMESTAMP value可选的 timestamp 参数是一个int 的Unix 时间戳,如未指定或是 null ,参数值默认为当本地时间。也就是说,其值默认为time() 的返回值。
* `strftime` and `strptime`: These functions are fundamental for converting between DATE / TIMESTAMP values and formatted strings, and vice-versaChapter 12 Dates and Times | STA 444/5 This is crucial when parsing CSV files, displaying data to users, or exchanging information between programsDate Format Functions – DuckDB Many systems, including DuckDB, offer robust implementations of these conversion utilitiestwekkel/htpdate HTTP Time protocol
* `formatdate` Function: In certain contexts, such as configuration templating with tools like Packer, a `formatdate` function allows you to convert a timestamp into a specified time format, making it easier to generate dynamic date stringstwekkel/htpdate HTTP Time protocol
