> The following tests tend to fail when using test-with-docker. What's common about them is that they're doing a time zone conversion.
> {code}
>  metadata.test_show_create_table.TestShowCreateTable.test_show_create_table[table_format: text/none]	1 min 23 sec	19
>  query_test.test_queries.TestHdfsQueries.test_hdfs_scan_node[exec_option: {'batch_size': 0, 'num_nodes': 0, 'disable_codegen_rows_threshold': 0, 'disable_codegen': False, 'abort_on_error': 1, 'debug_action': None, 'exec_single_node_rows_threshold': 0} | table_format: orc/def/block]	4.1 sec	58
>  query_test.test_scanners.TestOrc.test_type_conversions[exec_option: {'batch_size': 0, 'num_nodes': 0, 'disable_codegen_rows_threshold': 0, 'disable_codegen': False, 'abort_on_error': 1, 'debug_action': None, 'exec_single_node_rows_threshold': 0} | table_format: orc/def/block]	16 sec	58
>  ExprTest.TimestampFunctions
> {code}
> It turns out that people parse {{readlink(/etc/localtime)}} to find out the current time zone. This got noticeable when the ORC change landed (though I've seen that one come and go) and then very frequently when we changed time zone DBs. (Or so I think.)
> I have a simple change forthcoming.
