anyone with a code snippet for me?

I would use two regex first to make 01,02,03... from Jan,Feb,.. 
and
second to split the result.

I found this solution, letting the MySQL engine do the work:

   SELECT STR_TO_DATE('26/Apr/2011:13:21:58', '%d/%b/%Y:%H:%i:%S');

Maybe  there is an other short solution using the std.datetime 
and or
