  47 In order to run without DB access, this test will substitute '$fake_syspref'
  48 as your default date format.  Export environmental variable KOHA_TEST_DATE_FORMAT
  49 to override this default, or pass the value as an argument to this test script.

  51 NOTE: we test for the system handling dd=00 and 00 for TIME values, therefore
  52 you SHOULD see some warnings like:
