Why My Java Program Shows Wrong Timestamp?

It may due to you set up time zone wrongly if you are in Solaris or Unix machine. For the below example, if you use GMT[+/-] format instead of City or a valid timzone name, you will got wrong timestamp. Refer to my previous post about how to set TZ correctly.
