You can use different date formats. To support a date in a different locale, add a header locale=yourlocale and provide the locale in the header line. The locale can be in the dd/mm/yy or en_US format. If either the locale is not valid or the locale header is not present, the dates take the default locale. The default locale is the locale of the server you are importing the contracts from.
Format: locale=dd/mm/yy,ParentContract,Admincontractid,adf0,adf1,adf2,adf3,adf4,Description,adf5,Contractname,adf6,adf7,adf8,adf9,Costcenter,adf10,Dateordered,Totalcost,Noticedescription,adf11,adf12,Adminvendorid,VendorName,UserDocId,StartDate,EndDate
The locales can also be added at the end as shown below:
Format: ParentContract,Admincontractid,adf0,adf1,adf2,adf3,adf4,Description,adf5,Contractname,adf6,adf7,adf8,adf9,Costcenter,adf10,Dateordered,Totalcost,Noticedescription,adf11,adf12,Adminvendorid,VendorName,UserDocId,StartDate,EndDate,locale=dd/mm/yy
For example, use locale=en-us English-United States or locale=de-de for German-Germany
