The Google webmaster tools recently reported an issue with one of my sitemaps.
It was a warning for an invalid date. The date was set to 0000-00-00 00:00:00.
The links were all imported from an Excel spreadsheet and that is how the date was left on them. In the past this hasnt been an issue. But somewhere along the way the date 1969-01-01 cropped up instead of 0000-00-00
