Bug 95558 – glibc-2.3.4.20041102-r1: mktime fails to normalize the tm structure when tm_sec is out of range

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Laurent Pinchart 2005-06-09 07:14:10 UTC]

from man mktime:   
   
"If structure members are outside their legal interval, they will be   
normalized (so that, e.g., 40 October is changed into 9 November)."   
   
mktime fails to normalize the tm_sec member. It clamps its value to [0..59]   
instead. This causes problems in all programs that rely on that functionality, 
for instance to convert time between local time and UTC. KOrganizer is one 
such program. 
 

Reproducible: Always
Steps to Reproduce:
1. Emerge glibc-2.3.4.20041102-r1 
2. Run the attached test program 
Actual Results:  
tut: 1104534060, stm: 2005-01-01 00:00:59 0001 

Expected Results:  
tut: 1104534060, stm: 2005-01-01 00:01:00 0001
