commit 931555dfc97a20c94e7ca50d61373a4d10548a17
Author: Maxim Cournoyer <maxim.cournoyer@gmail.com>
AuthorDate: Tue Sep 12 10:14:32 2023 -0400

    gnu: qtbase: Reinstate date related tests.
    
    * gnu/packages/qt.scm (qtbase) [native-inputs]: Add tzdata-for-tests.
    [arguments]: Set the TZDIR and TZ environment variables, and reinstate the
    tst_qdate, tst_qtimezone and tst_qdatetime tests in the check phase.
    (qtbase-5) [source]: Replace qtbase-use-TZDIR.patch with
    qtbase-5-use-TZDIR.patch.
    * gnu/packages/patches/qtbase-use-TZDIR.patch: Refresh patch with upstream
    version, and preserve the old one for qtbase@5 as...
    * gnu/packages/patches/qtbase-5-use-TZDIR.patch: ... this.
    * gnu/local.mk (dist_patch_DATA): Register new patch.
    
    Series-changes: 2
    - Use old TZDIR patch for qtbase@5 (the new one doesn't apply)
