How to escape single quote in java's SimpleDateFormat

问题

I have a date input date like this: {ts '2012-08-13 02:30:01'}

I believe I can escape the invalid part with single quotes, but I have a single quote within the invalid part. How do I escape that? I tried a couple of patterns but it is not working.

Thanks,

According to the javadocs for SimpleDateFormat

Text can be quoted using single quotes (') to avoid interpretation. "''" represents a single quote.

So a format string like:

"'{ts '''yyyy-MM-dd HH:mm:ss'''}'"

should match {ts '2012-08-13 02:30:01'}

Have you tried escaping the single quote by another single quote? Otherwise the better way might be to exctract the relevant part (between the quotes) using a regular expression, and only then applying the SimpleDateFormat.
