Date and time formats are specified by date and time pattern strings. Within date and time pattern strings, unquoted letters from 'A' to 'Z' and from 'a' to 'z' are interpreted as pattern letters representing the components of a date or time string. Text can be quoted using single quotes (') to avoid interpretation. "''" represents a single quote. All other characters are not interpreted; they're simply copied into the output string during formatting or matched against the input string during parsing. The following pattern letters are defined (all other characters from 'A' to 'Z' and from 'a' to 'z' are reserved): Letter Date or Time Component Presentation Examples

你给的代码执行后抛出一个异常:java.text.ParseException: Unparseable date: "Mon Dec 01 17:04:45 CST 2003"
try {
long date = sdf.parse("Mon 12 01 17:04:45 CST 2003").getTime();
} catch (ParseException e) {
