Question

I have the following code in Java. I’ve been asked to port it to C++, however, I am not a Java developer. What would be the equivalent in C++:

public String formatDate( String string, Date time, TimeZone timeZone )
{
    Calendar calendar = Calendar.getInstance( timeZone );
    calendar.setTime( time );
    StringBuffer answer = new StringBuffer();
    SimpleDateFormat format = new SimpleDateFormat( string );
    format.format( calendar, answer, null );
    return answer.toString();
}

The following line is how it’s being called:

formatDate( "yyyy-MM-dd'T'HH:mm'Z'", new Date(), TimeZone.getTimeZone( "GMT" ));

The format string has ‘T’ and ‘Z’, which I cannot find much documentation on.

Answer 1

The T and Z are simply being inserted (note the quotes) and not being replaced as part of the formatting. Thus the above could give you

The Z would normally give you a time zone (e.g. +0000) if it wasn’t quoted.
