SimpleDateFormat turns 0000-00-00 into 0002-11-30 !

[Stephen]

The following code,

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
long t = sdf.parse("0000-00-00 00:00:00").getTime();
System.out.println(t);
Date d = new Date(t);
System.out.println(sdf.format(d));

outputs the following,

-62170185600000
0002-11-30 12:00:00

is this a bug in SimpleDateFormat or am I using it wrong to turn
a date string (eg. "2002-07-19") into a Long ?

You are messing up the date logic, day 0 and month 0 are values that should
never happen, and the parse method returns a strange value (i don't know
why..) the rest of the code is correct for realistic dates

Probably more than you need to know about DateFormat objects:

parse wants human-formatted dates, not 0-based ones for day and month.

Also, there never existed a year 0. The year before 1 AD was the year 1
BC (as all who followed the discussion on when the millenium really
started knows all too well).
