Hmmm, would say, that depends. Its probably not as fast as Integer.toString(), 
but IMHO its still pretty fast and quite comfortable (especially if you have to 
consider timezone conversion etc.). 

What I've seen is, that the way hibernate uses SimpleDateFormat is often 
inefficient and actually that results in bad performance. E.g. hibernate often 
creates a new SimpleDateFormat when it needs one. Better would be to clone a 
static instance (since pattern is the same) and adjust its timezone if 
neccessary. This would safe the relative expensive compilation of the 
underlying format pattern, which is done for each new instance of a 
simpledateformat ...
