Fixes <https://bugs.gnu.org/21906>. Mitigates <https://bugs.gnu.org/21903> and <https://bugs.gnu.org/21904>. Reported by: Zefram <zefram@fysh.org>. * module/srfi/srfi-19.scm (encode-julian-day-number) (decode-julian-day-number, date-week-number): Use 'floor-quotient' instead of 'quotient', and 'floor' instead of 'truncate', where appropriate. (time-utc->date): Ensure that the 'nanoseconds' field of the returned date is non-negative. (leap-year): Handle negative years properly, and reformulate the computation. (week-day): Handle negative years properly. Use 'floor-quotient' instead of 'quotient' where appropriate. (directives): In the handler for '~Y' format escapes, improve the handling of years outside of the range 0-9999. (read-directives): Add a FIXME comment to fix the '~Y' reader to handle years outside of the range 0-9999. * test-suite/tests/srfi-19.test: Import (srfi srfi-1). Use Guile's modern keyword notation in the 'define-module' form. Add more tests. |
