* date: Improve nanosecond supportDag-Erling Smørgrav2025-11-191-46/+102
| | | | | | | | | | | | | | | Add support for a field width, which defaults to 9 if unspecified or zero. If the width is not exactly 9, we have to either cut off digits or append zeroes to make up the difference. If the width is a dash, we pick a width based on the clock's reported resolution. This brings us in line with GNU coreutils.

* date: Add support for nanosecondsMateusz Piotrowski2024-05-021-27/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces support for a conversion specification for nanoseconds. The format of %N is meant to be compatible with that of GNU date. The nanoseconds conversion specification is implemented directly in date(1) instead of libc (in strftime(3)) to avoid introducing non-standard functions to libc at this time and modifying struct tm. Apart from introducing the nanoseconds conversion specification, this patch brings the following changes: - The "ns" format for ISO 8061 dates is now unlocked. E.g., date -Ins prints: 2024-04-22T12:20:28,763742224+02:00 - The -r flag when fed a file is now aware of the nanosecond part of the last modification time. - date(1) is now able to set the time with nanosecond precision. It is not possible as of now to do that by specifying nanoseconds directly via the command-line arguments. Instead, the -r flag can be used. - date(1) is now using the clock_gettime(3) family of functions instead of ctime(3) family of functions where possible.

| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

| | | | | | | | | | | | | | | | | This structure is not part of POSIX.

Remove dead error handling code. Also use NULL for a nul-pointer instead of integer 0. While there, change all pieces of code that only use tv_sec to use time(3), as this provides less overhead.
