The unformatted date in Excel appears to be in the Julian format.

Dates in Excel are not stored in Julian format. They are stored as the number of days from a 1900 epoch with 1900 treated as a leap year.

Both WritExcel and ParseExcel provide utility functions for dealing with dates in this format but I'd recommend the DateTime::Format::Excel module.
