It is a niche networking package for environments where NTP is blocked, unavailable, or inconvenient but outbound HTTP works. ### Projektgeschichte The upstream site and repository describe HTP as synchronizing time with web servers as reference sources. htpdate retrieves date and time through HTTP requests, can behave similarly to a browser, works through proxy servers, and can run as a daemon for ongoing synchronization. The project preserves a pragmatic limitation in its own documentation: usual accuracy is within about 0.5 seconds and can improve with multiple servers, but users needing better time discipline should use an NTP-family package. That framing explains htpdate's evolution as a fallback or constrained-network utility rather than a replacement for NTP, OpenNTPD, or chrony. ### Adoptionsgeschichte The input package facts record htpdate in Homebrew, Debian, Ubuntu, MacPorts, Nix, and Alpine. That packaging spread is notable for a small tool because its value is situational: it becomes useful exactly on machines and networks where the usual UDP-based time-sync path is not available. ### Wie es verwendet wird htpdate is used to query one or more web servers, estimate clock offset from HTTP date headers, and either report or set/adjust local time. The man page and README emphasize proxy support, daemon use, IPv4/IPv6 options, HTTP/1.0 versus HTTP/1.1 behavior, and the tradeoff between convenience and precision. ### Warum Paket-Nerds sich dafür interessieren For package nerds, htpdate is interesting because it is the kind of tiny utility that justifies a package slot through an edge case. It exists for restricted networks, proxy-only hosts, rescue scenarios, and systems where installing a full time-sync stack is more machinery than the job requires. ### Zeitleiste - 2021: The twekkel/htpdate tag stream includes v1.3.0 from December. - 2024: The tag stream includes v2.0.0 from September. - 2024: Alpine package metadata records htpdate 2.0.0 in the community repository. - Package-manager era: The input package facts record htpdate in Homebrew, Debian, Ubuntu, MacPorts, Nix, and Alpine. ### Related projects - htpdate is related to NTP clients such as ntpdate, ntpd, OpenNTPD, and chrony, but trades precision for HTTP reachability and proxy compatibility. The same maintainer also publishes `httpdate`, another HTTP-based time synchronization tool with a precision-oriented approach. ### Quellen - - - - - - - - ## Sicherheitshinweise broad file, network, media, or database tool signal. - **Geiger-Risiko:** blue / mittel - broad file, network, media, or database tool signal ## Andere Paketmanager-Einträge - Debian apt - htpdate - 1.3.7-2+b2: normalized package name match | Debian stable package indexes: htpdate from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | HTTP based time synchronization tool | https://github.com/twekkel/htpdate - Nix - htpdate: normalized package name match | nixpkgs package indexes: pkgs/by-name/ht/htpdate/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - htpdate - 1.3.7-2build2: normalized package name match | Ubuntu 24.04 LTS package indexes: htpdate from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | HTTP based time synchronization tool | https://github.com/twekkel/htpdate - apk - htpdate - 2.0.0-r0: normalized package name match | Alpine Linux edge package indexes: htpdate from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | HTTP Time protocol | https://github.com/twekkel/htpdate - apk - htpdate-doc - 2.0.0-r0: normalized package name match | Alpine Linux edge package indexes: htpdate-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | HTTP Time protocol (documentation) | https://github.com/twekkel/htpdate - apk - htpdate-openrc - 2.0.0-r0: normalized package name match | Alpine Linux edge package indexes: htpdate-openrc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | HTTP Time protocol (OpenRC init scripts) | https://github.com/twekkel/htpdate - MacPorts - htpdate: normalized package name match | MacPorts ports tree: net/htpdate/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
