| Summary | 0000664: localtime_r() has incomplete daylight and timezone requirements | ||||
| Description | In the Issue 6 change history on the localtime() page there is this entry: IEEE Std 1003.1-2001/Cor 2-2004, item XSH/TC2/D6/56 is applied, adding a requirement that if localtime_r() does not set the tzname variable, it shall not set the daylight or timezone variables. On systems supporting XSI, the daylight, timezone, and tzname variables should all be set to provide information for the same timezone. This updates the description of localtime_r() to mention daylight and timezone as well as tzname. It is apparent from this that the intention is that the daylight and timezone variables should always be kept consistent with tzname. However, the normative text only requires that if localtime_r() does not set tzname then it does not set daylight and timezone. There is no requirement that if localtime_r() sets tzname then it also sets daylight and timezone. The ctime() page, as updated by Issue 7 TC1, has the same problem. | ||||
| Desired Action | Change: If localtime_r() does not set tzname, it shall not set daylight and shall not set timezone. to: If localtime_r() sets tzname, it shall also set daylight and timezone. If localtime_r() does not set tzname, it shall not set daylight and shall not set timezone. On Page: 715 Line: 24085 Section: ctime(), after applying XSH/TC1/0066, change: If ctime_r() does not set tzname, it shall not set daylight and shall not set timezone. to: If ctime_r() sets tzname, it shall also set daylight and timezone. If ctime_r() does not set tzname, it shall not set daylight and shall not set timezone. | ||||
