unistd.h

Following Paul Eggert's (eggert(a)twinsun.com) advice, I ftped the tz*95 data from elsie.nci.nih.gov. However, all the little utilities #include the file 'private.h', which in turn #includes a file called 'unistd.h', which unfortunately is not available on my system. Is this file crucial to any of the functions in the package, or can I safely delete the reference without ill side effects?

FYI: date_parse - simple date parsing routine and programs

Newsgroups: alt.sources From: jef(a)netcom.com (Jef Poskanzer) Subject: date_parse - simple date parsing routine and programs Message-ID: <jefD3uzqC.Mos(a)netcom.com> Reply-To: Jef Poskanzer <jef(a)netcom.com> Organization: Paratheo-Anametamystikhood Of Eris Esoteric Date: Sat, 11 Feb 1995 23:25:24 GMT Lines: 2048 Sender: jef(a)netcom18.netcom.com date_parse - date parsing routine and programs version 1.0 of 11feb95 For a while now I've been somewhat unhappy with the various date-parsing routines available - yacc-based, lex-based, ad-hoc. Large code size and not very portable are the main complaints. So I wrote a new one that just does a bunch of sscanf's until one matches. Slow, but small and portable. To figure out what formats to support I did a survey of Date: lines in a bunch of Usenet articles. The following two formats accounted for more than 99% of all articles: N mth YYYY HH:MM:SS ampm zone wdy, N mth YYYY HH:MM:SS ampm zone I added Unix ctime() format and a few others: wdy mth N HH:MM:SS ampm zone YYYY HH:MM:SS ampm zone N mth YYYY N mth YYYY HH:MM:SS ampm No-zone, no-seconds, and no-am/pm versions of each are also supported. Note that dd/mm/yy and mm/dd/yy are NOT supported - those formats are dumb. Aside from the date-parsing routine, this package includes some programs that exercise it: o date_sort - sort a file's lines by date o date_order - order a list of files by netnews/mail-format Date: lines o deltime - subtract two times and show the difference o xmit_time - figure transmission time of netnews articles - - - - - - - - - - #! /bin/sh # This is a shell archive, meaning: # 1.

X.PP XThis does not change or rearrange the actual files in any way. XAll it does it produce a new list of the fileNAMEs, sorted by the dates Xin the files.

X.SH SPEED X.PP XThe implementation is just a bunch of sscanf's - small and portable, but slow. XStill, it's not that bad. XOn a SPARCstation 2 parsing ~70000 random dates, the average time Xwas 0.94 msec/date. XThis compares surprising well with the lex-based date parser from Xthe MH package, which took 0.34 msec/date in the same test. XThe yacc-based parser used in many netnews packages is about halfway Xbetween the two.

XBe careful to put the dates in quotes if they contain spaces. XThe output format is dddd hh:mm:ss. X.PP XTimes earlier than 1970 cannot Xbe handled, because that's as far back as the internal Unix time format goes.
