System Time Zone…………….: UTC+8 Current System Date………….: 2010-01-18 Current System Time………….: 15:01:58
System time zone seems to be correct
Current User Date (Entered)…..: 2010-01-18 Current User Time (Entered)…..: 07:59:06 Current User Time Zone (Entered): CET
Current User Time (Conversion)..: 2010-01-18 Current User Date (Conversion)..: 08:01:58
