The net-telent-date Reference Manual

1 Introduction

Most of the code in this package is parse-time.lisp, which was
originally written by Jim Healy in June 1987, and has been lifted
wholesale from CMUCL.

The rest of it is a few useful functions for printing dates in
standard(sic) formats.  See documentation strings for
universal-time-to-http-date, universal-time-to-rfc2822-date, dayname,
monthname.

Thanks to Kevin Rosenberg for bouncing ideas off, for the initial
universal-time-to-rfc2822-date implementation, and for Debian
packaging

5.1.1 Macros

Macro: with-date UTIME ZONE &body BODY

UTIME is a universal-time, ZONE is a number of hours offset from UTC, or NIL to use local time. Execute BODY in an environment where SECOND MINUTE HOUR DAY-OF-MONTH MONTH YEAR DAY-OF-WEEK DAYLIGHT-P ZONE are bound to the decoded components of the universal time

Macro: with-decoding (UTIME &optional ZONE) &body BODY

UTIME is a universal-time, ZONE is a number of hours offset from UTC, or NIL to use local time. Execute BODY in an environment where SECOND MINUTE HOUR DAY-OF-MONTH MONTH YEAR DAY-OF-WEEK DAYLIGHT-P ZONE are bound to the decoded components of the universal time

5.1.2 Functions

Function: dayname STREAM ARG COLON-P AT-P &optional WIDTH MINCOL COLINC MINPAD PADCHAR

Package

net.telent.date

Source

date.lisp (file)

Function: parse-time TIME-STRING &key START END ERROR-ON-MISMATCH PATTERNS DEFAULT-SECONDS DEFAULT-MINUTES DEFAULT-HOURS DEFAULT-DAY DEFAULT-MONTH DEFAULT-YEAR DEFAULT-ZONE DEFAULT-WEEKDAY

Tries very hard to make sense out of the argument time-string and returns a single integer representing the universal time if successful. If not, it returns nil. If the :error-on-mismatch keyword is true, parse-time will signal an error instead of returning nil. Default values for each part of the time/date can be specified by the appropriate :default- keyword. These keywords can be given a numeric value or the keyword :current to set them to the current value. The default-default values are 00:00:00 on the current date, current time-zone.
