reference implementation did not handle DST and time zones properly and relied on non-R5RS-isms like passing reals to `quotient'. For Guile, some additional fixes were needed because of the incomplete numeric tower implementation. See also srfi-19.test. * srfi-19.scm (date-zone-offset): Fixed typo in export clause. (add-duration): Renamed from priv:add-duration. (priv:time-normalize!): Handle fractional nanoseconds; remove duplicate definition. (priv:current-time-tai): Fixed typo. (time=?, time<=?): Fixed typos. (time-tai->time-utc, time-utc->time-tai, time-utc->time-monotonic): Use make-time-unnormalized instead of make-time when uninitialized time fields are used. (set-date-nanosecond!, set-date-second!, set-date-minute!, set-date-hour!, set-date-day!, set-date-month!, set-date-year!, set-date-zone-offset!): Define. (priv:local-tz-offset): Take an extra argument in order to handle DST effects. (time-utc->date, time-tai->date, time-monotonic->date): Handle the changed signature of priv:local-tz-offset. Don't pass non-integer arguments to quotient (non-R5RS, not supported by Guile). (date->time-utc): Ensure that seconds in a date structure are always exact integers. Handle DST properly. (current-date, julian-day->date, modified-julian-day->date): Handle the changed signature of priv:local-tz-offset. (julian-day->time-utc): Reverted earlier inexact->exact hack; make-time now handles inexact arguments. (priv:locale-print-time-zone): At least print the numerical time zone. (priv:integer-reader): Fixed named let iteration. (priv:read-directives): Use set-date-month! instead of priv:set-date-month! etc. (string->date): Handle DST properly. |

This directory includes most of Guile's SRFI support. -*- text -*- For more details about what SRFI means, and what the various numbers stand for, please refer to the SRFI homepage at http://srfi.schemers.org The following SRFIs are supported (as of 2001-06-06 -- 'martin): SRFI-0: cond-expand Supported by default, no module needs to get used. SRFI-1: List Library A full toolbox of list processing procedures. (use-modules (srfi srfi-1)) will make them available for use. SRFI-2: and-let* (use-modules (srfi srfi-2)) to make and-let* available. SRFI-6: open-input-string, open-output-string and get-output-string (use-modules (srfi srfi-6)) to make these available. (Currently, these procedures are available without using the module, but the procedures might be factored out of the core library in the future.) SRFI-8: receive (use-modules (srfi srfi-8)) to make receive available. SRFI-9: define-record-type A mechanism for defining record types. (use-modules (srfi srfi-9)) makes this syntactic form available. SRFI-10: #,() The hash-comma reader extension. (use-modules (srfi srfi-10)) activates the extension. SRFI-11: let-values and let-values* Syntactic extensions for handling multiple values. (use-modules (srfi srfi-11)) makes these syntactic forms available. SRFI-13: string library A lot of (more or less) useful string processing procedures. (use-modules (srfi srfi-13)) loads the procedures. SRFI-14: character-set library Character-set library. (use-modules (srfi srfi-14)) loads the procedures and standard variables. SRFI-16: case-lambda Syntactic form which permits writing functions acting different according to the number of arguments passed. (use-modules (srfi srfi-16)) makes this syntactic form available. SRFI-17: Generalized set! Guile supports generalized set! by default, but this module makes it fully compliant to the SRFI. (use-modules (srfi srfi-17)) loads the procedures. SRFI-19: Time Data Types and Procedures A lot of data types and procedures for dealing with times and dates. (use-modules (srfi srfi-19)) loads the procedures. SRFI-23: Error reporting mechanism (draft) This SRFI is still in draft status, but Guile fully supports it already. No need to load any module.
