Investigate why Coin macOS VMs don't know CET as a zone-abbreviation



    • Type: Task
    • Status: Reported
    • Priority: P3: Somewhat important
    • Resolution: Unresolved
    • Affects Version/s: 5.12
    • Fix Version/s: None
    • Component/s: Core: Date/Time
    • Labels:
    • Environment:

      macOS, particularly 10.13, but older (supported) versions are interesting, too.

    • Platform/s:
    • Technical Risk:


      When Erik Verbruggen first tested macOS 10.13, he found it got CET as the abbreviation for Europe/Berlin, at odds with various tests which expect macOS to use GMT+offset for it.  However, when we came to launch macOS 10.13 on Coin (for 5.12 and later), it got GMT+offset the same as all our older version of macOS.  So clearly there's something we could do on the Coin VMs to get the same set-up Erik had when he first tried; but we don't know what it is. That might even work in older versions, saving us the need for the hacks to expect GMT+offset. So we need someone proficient in macOS admining to investigate.

      Tony Sarajärvi has set up debug VMs (with the usual macOS credentials) for investigation.

      • macOS 10.12:
      • macOS 10.13:

      The tests that implicate this are the ones this review would un-blacklist (once we know how to change the #if-ery in them to suit the revised VM config): tst_QDateTime::timeZoneAbbreviation() and tst_QLocale::formatTimeZone().
