    Deprecate date options with a time of day setting.
    
    Removing the only use, an example in hello-world.scm. GnuCash doesn't
    use this value in any of its own report options and the feature will
    be removed in GnuCash 5.
    
    Related to bug 798297 Pref "Use 24-hour clock" obsolete?.
