fmsync Successfully Able to Set Dates not Displayable by WIndows

If you set a date such as created: 3035-01-01T00:00:00 fmsync seems able to try and set it without any errors or warnings. However, Windows Explorer displays this date as blank. If this service is WIndows-only, should we be validating the date so that we error if we try and set it to something Windows cannot support?
