-Subject: [PATCH] time: make the ParseInLocation test more robust
-
-The tzdata 2017a update (2017-02-28) changed the abbreviation of the
-Asia/Baghdad time zone (used in TestParseInLocation) from 'AST' to the
-numeric '+03'.
-
-Update the test so that it skips the checks if we're using a recent
-tzdata release.
-
-Fixes #19457
