WORK AROUND Use "/" as the date field separator. Note that "/" is the default separator for the ar locale. masayoshi.okutsu@Eng 1999-12-20

EVALUATION SimpleDateFormat uses DecimalFormat in a locale sensitive way. In ar locale, "31-" of "31-������-00 08:00 ���" is interpreted as the negative value, -31. Then, the parser fails to parse the rest of the string since it doesn't match the pattern "dd-MMM-yy". masayoshi.okutsu@Eng 1999-12-20 It's not clear about the locale dependecy on date fields at the API spec level. masayoshi.okutsu@Eng 2000-02-10
