imagine have proccess creates 1000 entities each second. each of these entities call setter : newentity.setdate(new date()); 1) possible 2 entities recieve same date? or safe assume unique identifier effect date field? 2) if answer question #1 :"yes" - let's make minor tweak: lets create function: public static synchronized date getdate() { return new date(); } will work now? newentity.setdate(getdate()); 3) system.nanotime()? edit 4) : public static synchronized date getdate() { thread.sleep(1000); return new date(); } thanks. a simple test shows 2 consecutive calls new date() can return same date. making method synchronized won't make difference. if need unique id, use atomicinteger counter , return counter.getandincrement(); new ids. ps: using system.nanotime() won't either resolution os , processor dependent , low enough 2 consecutive calls can return same result too. edit your 4th proposal slee
