Incorrect UTC conversion of CST timestamps by the 'date' utility
Last modified: 2007-11-30 17:07:30 EST
Description of problem: ~> date -u -d 'Nov 19 11:27 CST 2007' Mon Nov 19 17:27:00 UTC 2007 Note: CST is China Standard Time. The correct value was: Mon Nov 19 03:27:00 UTC 2007 Version-Release number of selected component (if applicable): ~> rpm -q tzdata tzdata-2007h-1.el4 ~> rpm -q coreutils coreutils-5.2.1-31.7 How reproducible: Fully reproducible. Steps to Reproduce: 1. date -u -d 'Nov 19 11:27 CST 2007' 2. 3. Actual results: Mon Nov 19 17:27:00 UTC 2007 Expected results: Mon Nov 19 03:27:00 UTC 2007 Additional info: Found first on RHEL 3... with: tzdata-2003c-1 and coreutils-4.5.3-26
As is mentioned in sourcecodes of getdate.y (coreutils-{version}/lib/) is impossible to make 3 letters long shortcuts of date without conflicts. For example - EST is US Eastern standard time and Eastern standard time in Australia - time zones of course differ. This one is conflict between China standard time and US Central standard time. I will citate source code of coreutils: "You cannot rely on getdate to handle arbitrary time zone abbreviations; use numeric abbreviations like `-0500' instead." So sorry, can't help, NOTABUG
