ANTLR 3 parsing problem

I have written an ANTLR 3 grammar for parsing TaskJuggler III bookings files (see below).

On line

project prj "Sample project" "1.0" 2010-10-24-00:00-+0200 - 2010-11-23-09:00-+0100 {

I'm getting following errors:

line 1:42 mismatched character '-' expecting set '0'..'9'

line 1:48 mismatched character ':' expecting set '0'..'9'

line 1:67 mismatched character '-' expecting set '0'..'9'

line 1:73 mismatched character ':' expecting set '0'..'9'

Thereafter, an OutOfMemory error occurs.

Here is the relevant part of the grammar:

bookingsFile returns [DefaultBookingsFile bookingsFile]

:

    {

        bookingsFile = new DefaultBookingsFile();

    }

    projectHeader

    projectIds

    (resourceDeclaration)*

    (task)*

    (

        suppStmt=supplementStatement 

{bookingsFile.addSupplementStatement( $suppStmt.suppStmt ); }

    )*

;

projectHeader

:

    'project prj "' ANY_TEXT '" "1.0"' TJ3_BOOKING_TIME '-' 

TJ3_BOOKING_TIME '{'

    '}'

;

TJ3_BOOKING_TIME

: DIGIT DIGIT DIGIT DIGIT '-' DIGIT DIGIT '-' DIGIT DIGIT 

'-' DIGIT DIGIT ':' DIGIT DIGIT '-' TIMEZONE

;

TIMEZONE

: ('+'|'-')DIGIT DIGIT DIGIT DIGIT

;

Question: What am I doing wrong?

Thanks in advance

Your rule:

TJ3_BOOKING_START_TIME

  ;

does not match this part of your input:

" ... 2010-10-25-00:00-+0200 ... "
//                    ^^

The -+ part is not accounted for in your rule.

EDIT

Try something like this:

grammar Bookings;

bookingsFile
  :  Project Prj String String Time Hyphen Time OpenParen CloseParen EOF
  ;

Project
  :  'project'
  ;

Prj
  :  'prj'
  ;

OpenParen
  :  '{'
  ;

CloseParen
  :  '}'
  ;

Hyphen
  :  '-'
  ;

String
  :  '"' ~'"'* '"'
  ;

Time
  :  D D D D '-' D D '-' D D '-' D D ':' D D '-+' D D D D
  ;  

fragment    
D
  :  '0'..'9'
  ;

Space   
  :  (' ' | '\t' | '\r'? '\n'){$channel=HIDDEN;}
  ;

Interpreting the source:

project prj "Sample project" "1.0" 2010-10-25-00:00-+0200-2010-11-24-09:00-+0100 {
}

yields the parse-tree:
