Description David Dombek 2003-04-07 13:38:51 EDT
Description of problem:
The date command as provided by gnu-sh-utils 2.0.11 does not properly calculate 
the date for yesterday.

date --date=yesterday does NOT work with changes from Standard time to Daylight 
savings time

[root@adsfa root]# date --date=yesterday  
Sat Apr  5 23:27:59 EST 2003

[central@adsfa central]$ date      
Mon Apr  7 00:33:30 EDT 2003


Version-Release number of selected component (if applicable):
2.0.11 

How reproducible:
ALL the time

Steps to Reproduce:
1. Set date on computer to Sat, April 7, between 12-1am
2. Run date --date=yesterday
3.
    
Actual results:
see above

Expected results:
The date program should properly caluclate the date.  It appears the date 
command is just subtracting 24hours from the said time.  This is incorrect.

Additional info:

This may also have a problem in other timezones as Europe changes before the US.

We don't ship coreutils in Red Hat Linux 9.  Perhaps you meant coreutils 4.5.3.
Comment 2 Tim Waugh 2003-04-07 13:51:42 EDT
Reported upstream.
Comment 3 David Dombek 2003-04-07 14:04:09 EDT
Sorry it is sh-utils.  I thought I selected the correct name.

Comment 4 Tim Waugh 2003-04-07 15:51:34 EDT
I made a mistake typing 'We don't ship coreutils in Red Hat Linux 9'; I meant to
write 'We don't ship sh-utils in Red Hat Linux 9'.  coreutils is the correct
component.
