Description Jose M. daLuz 2006-02-21 00:50:35 UTC
Originally I had a calendar that displayed Saturday as the first day of the
week, then switching from no locale set to LC_ALL="en_US" the first day became
Monday -- in both cases it should have been Sunday. Here is the locale data:

LC_ALL="" locale -k -c LC_TIME
LC_TIME
abday="Sun;Mon;Tue;Wed;Thu;Fri;Sat"
day="Sunday;Monday;Tuesday;Wednesday;Thursday;Friday;Saturday"
abmon="Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec"
mon="January;February;March;April;May;June;July;August;September;October;November;December"
am_pm="AM;PM"
d_t_fmt="%a %b %e %H:%M:%S %Y"
d_fmt="%m/%d/%y"
t_fmt="%H:%M:%S"
t_fmt_ampm="%I:%M:%S %p"
era=
era_year=""
era_d_fmt=""
alt_digits=
era_d_t_fmt=""
era_t_fmt=""
time-era-num-entries=0
time-era-entries=""
week-ndays=7
week-1stday=19971130
week-1stweek=4
first_weekday=7
first_workday=1
cal_direction=1
timezone=""
date_fmt="%a %b %e %H:%M:%S %Z %Y"
time-codeset="ANSI_X3.4-1968"

week-1stday=19971130 which is a Sunday. first_weekday=7 which is Saturday,
which is very wrong -- it should be 1 instead. This combo makes Saturday first
day of the week.

LC_ALL=en_US locale -k -c LC_TIME
LC_TIME
abday="Sun;Mon;Tue;Wed;Thu;Fri;Sat"
day="Sunday;Monday;Tuesday;Wednesday;Thursday;Friday;Saturday"
abmon="Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec"
mon="January;February;March;April;May;June;July;August;September;October;November;December"
am_pm="AM;PM"
d_t_fmt="%a %d %b %Y %r %Z"
d_fmt="%m/%d/%Y"
t_fmt="%r"
t_fmt_ampm="%I:%M:%S %p"
era=
era_year=""
era_d_fmt=""
alt_digits=
era_d_t_fmt=""
era_t_fmt=""
time-era-num-entries=0
time-era-entries="S"
week-ndays=7
week-1stday=19971201
week-1stweek=4
first_weekday=1
first_workday=1
cal_direction=1
timezone=""
date_fmt="%a %b %e %H:%M:%S %Z %Y"
time-codeset="ISO-8859-1"

week-1stday=19971201 which is a Monday, so with first_weekday=1 Monday becomes
the first day of the week in the calendar, which in the US is wrong.
week-1stday should be the same as in LC_ALL="" above.

I'm running glibc 2.3.5 on Gentoo 2005.1/AMD64, but other Gentoo users running
2.3.6 have the same problem. I've already reported this on Gentoo bugzilla and
was directed to report upstream.

Comment 3 Jose M. daLuz 2006-03-13 02:33:51 UTC
I updated to glibc 2.4. The locale data is updated and now Monday is the
first_weekday for the C locale, en_US and en_US.UTF-8. For the US this should
still be Sunday with first_workday as Monday.
Comment 4 Denis Barbier 2006-03-13 19:19:25 UTC
No, there is no such change in the C locale in glibc 2.4.
Comment 5 Jose M. daLuz 2006-03-14 04:19:02 UTC

> No, there is no such change in the C locale in glibc 2.4.

Sorry, I mistook an empty locale for the C locale. You're quite right. So this
problem remains unchanged.
Comment 6 Jose M. daLuz 2006-11-27 21:33:05 UTC
With glibc 2.5, the problem seems to be fixed:

OK. I will reproduce some (I think) useful messages:

http://bugs.gentoo.org/show_bug.cgi?id=120995#c21

I'm on glibc 2.5 and I still have first_weekday=7 for LC_ALL="".  For
LC_ALL="en_US" I get the correct first_weekday=1.

Related: bug <a href="http://sources.redhat.com/bugzilla/show_bug.cgi?id=181">
181 </a>.
The patch in the related bug "c-first-weekday.diff" should patch the problem
where first_weekday=7 in the POSIX locale. POSIX locale is the default for
LC_TIME when LC_ALL="".
Comment 12 Ulrich Drepper 2007-09-23 23:14:37 UTC
I have no idea what people complain here.  They are absolutely incapable of
specifying a problem.  Just showing some program output is in no universe a
suitable way.

The current libc code shows a Sunday as the first day in the US locale and
Monday as the first day in the the Spanish locale.  The former is definitely
correct and the latter is what people requested in the past.
