Timestamps not supported in dynamic mode: java.lang.ArithmeticException

Way to reproduce:
1. Open the attached dataset
2. Open the Timeline

The nodes have start attributes like "1208119831". Note that the value reported by the exception does not exist in the dataset. Illegal cast?

java.lang.ArithmeticException: Value cannot fit in an int: 55615500677
