* date: Improve nanosecond supportDag-Erling Smørgrav2025-11-113-53/+147
| | | | | | | | | | | | | 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. PR: 287080 MFC after: 1 week Reviewed by: 0mp Differential Revision: https://reviews.freebsd.org/D53667

* date: Add support for nanosecondsMateusz Piotrowski2024-04-263-35/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
