Add DurationNano, DurationUnits, DurationISO8601, TimeUnix, TimeUnixNano, and TimeRFC1123: wrappers around time.Duration and time.Time that marshal to the wire formats that json `format:` struct tag options (format:nano, format:units, and so on) used to produce with github.com/go-json-experiment/json. Go 1.27's encoding/json rejects format tag options outright, and the module moved its support behind a global experimental option that its documentation says will be removed (see golang/go#71631). Struct tags are also only honored by the marshaler that happens to encode the struct, so any stdlib encoding/json call reaching a tagged struct, including generated MarshalJSON methods, breaks under Go 1.27. These types instead carry their wire format with them: they implement both the v1 json.Marshaler/Unmarshaler and the module's MarshalerTo/UnmarshalerFrom interfaces and produce identical bytes under the standard library and the module, on Go 1.26 and Go 1.27. Tests verify byte-for-byte parity against the module's format tag encodings across randomized values. Unmarshal is additionally lenient where the legacy standard library produced a different encoding for the underlying type because it ignored the tags: the Time types also accept RFC 3339 strings and the string-formatted Duration types also accept nanosecond counts, so previously persisted data remains readable. The tailscale corp repo will migrate its format tag uses to these types; this repo has none.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
