The problem is that we're calculating the timezone relative to 01/01/2000, but the VET timezone changed from -4 hours to -4:30 hours on 12/09/2007. According to the spec, section 15.9.1.9 states "the time since the beginning of the year", presumably meaning the *current* year. Change the calculation to be based on whatever the current year is, rather than a canned date.
