I have date string and i need to convert that to date with specific format.
for example: dattime="2017-12-12 11:12:00";
date {
match =\> ["dattime", "yyyy-MM-dd HH:mm:ss"]
target =\> "dattime"
}

Formatting a timestamp in a specific format is something that should be done by the presentation layer so I think you're focusing on the wrong thing.
That said, the value produced by the date filter will be of a timestamp type that I think has methods for formatting (probably named strftime). If so you can use a ruby filter to call that method and format the timestamp in any way supported by the date library.
