    Default java.lang.IllegalArgumentException: Cannot format given Object as a Date

    Hi All,

    I would like to ask for help inorder to fix the error that I'm encountering. When trying to convert the time zone of a date I encountered the log below.

    java.lang.IllegalArgumentException: Cannot format given Object as a Date

    Here is what my code looks like:

    1. First I will get the date from the email header by the following code.

    String messageDate = (String) mail.headers["Date"];

    Output: Wed, 4 Jun 2014 18:30:05 +0800

    2. Next I will convert the timezone to EST.

    SimpleDateFormat timeZoneConvert = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z");

    timeZoneConvert.setTimeZone(TimeZone.getTimeZone(" EST"));

    String l_MailDateEST = timeZoneConvert.format(messageDate.trim());

    Once the code run I encounter the said error.

    Hoping for your help,

    Many Thanks,
    Kenneth

    Read the API for SimpleDateFormat and the classes it inherits from - to parse a String into a Date object, use the parse method. To convert the Date into a String, use the format method. The call to format(Object object) is inherited from the Format class, and is equivilent to
         format(obj, new StringBuffer(), new FieldPosition(0)).toString();
    and the API for this method states:
    Overrides Format. Formats a time object into a time string. Examples of time objects are a time value expressed in milliseconds and a Date object.
