Convert to UNIX timestamp error

Question

I used this to get the timestamp

long epoch = new java.text.SimpleDateFormat ("dd/MM/yyyy HH:mm:ss").parse("09/22/2008 16:33:00").getTime();

It returns 989929568.

Then I used online converter to change this number back to standard time,

what I get is

05 / 15 / 01 @ 12:26:08pm

, not

09/22/2008 16:33:00

What is happening?

Answer 1

change pattern to

MM/dd/yyyy HH:mm:ss

because 22 cannot be month
