Please use the regular Red Hat support channels https://www.redhat.com/support to help to prioritize the bug fix appropriately. The problem is caused by code in the parsetime subprogram in parsetime.y . exectm is moved to currtm after exectm.tm_isdst is set to -1. Nothing ever resets currtm.tm_isdst to either 0 or 1. When execution reaches line 508, currtm.tm_isdst is still -1, causing the test to pass, reducing the scheduled time by one hour. The proposed fix moves exectm to currtm before exectm.tm_isdst is set to -1. The proposed fix (based on line numbers in at-3.1.10-48.el6.i686 is 479a480 > memcpy(&currtm,&exectm,sizeof(currtm)); 482d482 < memcpy(&currtm,&exectm,sizeof(currtm)); I do not think this is proper fix either. The dst correction is incorrect. I committed the proper fix to the current Fedora rawhide package. I am sorry that I have to repeat that if you need the fix in the RHEL package, please report it via regular Red Hat support channels so it can be properly prioritized. Ah I see there is already such report. If it was not you who opened it, please open it too so the priority is raised. *** This bug has been marked as a duplicate of bug 1320322 *** |
