Here is the GNU time home page:

Here are the compressed sources:
  https://ftp.gnu.org/gnu/time/time-1.10.tar.gz   (832KB)
  https://ftp.gnu.org/gnu/time/time-1.10.tar.xz   (572KB)

Here are the GPG detached signatures:
  https://ftp.gnu.org/gnu/time/time-1.10.tar.gz.sig
  https://ftp.gnu.org/gnu/time/time-1.10.tar.xz.sig

Use a mirror for higher download bandwidth:

Here are the SHA256 and SHA3-256 checksums:

  SHA256 (time-1.10.tar.gz) = 6MKftKtZnYR45B6GGPUNuK7enJCvJ9DS7yiuUNXeCcM=
  SHA3-256 (time-1.10.tar.gz) = zDjyfyzfABsSZp7lwXeYr368VzjZMkNPUJNnfpIakGk=
  SHA256 (time-1.10.tar.xz) = cGv3uERMqeuQN+ntoY4dDrfCMnrn2MLOOkgjxfgMexE=
  SHA3-256 (time-1.10.tar.xz) = U/Z0kMenoHkc7+rkCHMeyku8nXvIPppoQ2jq3B50e/A=

Verify the base64 SHA256 checksum with 'cksum -a sha256 --check'
from coreutils-9.2 or OpenBSD's cksum since 2007.

Verify the base64 SHA3-256 checksum with 'cksum -a sha3 --check'
from coreutils-9.8.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify time-1.10.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   rsa4096/8CE6491AE30D7D75 2024-03-11 [SC]
        Key fingerprint = 2371 1855 08D1 317B D578  E5CC 8CE6 491A E30D 7D75
  uid                 [ultimate] Collin Funk <collin.funk1@gmail.com>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --locate-external-key collin.funk1@gmail.com

  gpg --recv-keys 8CE6491AE30D7D75

  wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=time&download=1' | gpg --import -

As a last resort to find the key, you can try the official GNU
keyring:

  wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
  gpg --keyring gnu-keyring.gpg --verify time-1.10.tar.gz.sig

NEWS

* Noteworthy changes in release 1.10 (2026-04-14) [stable]

** Bug fixes

  'time --help' no longer incorrectly lists the short option -h as being

  'time --help' no longer emits duplicate percent signs in the description of
  the --portability option.
  [bug introduced in time-1.8]

  time now opens the file specified by --output with its close-on-exec flag set.
  Previously the file descriptor would be leaked into the child process.
  [This bug was present in "the beginning".]

  time no longer appends the program name to the output when the format string
  contains a trailing backslash.
  [This bug was present in "the beginning".]

** Improvements

  time now uses the more portable waitpid and getrusage system calls
  instead of wait3.

  time can now be built using a C23 compiler.

  time now uses unlocked stdio functions on platforms that provide them.
