Golang XML Unmarshal and time.Time fields

I have XML data I am retrieving via a REST API that I am unmarshal-ing into a GO struct. One of the fields is a date field, however the date format returned by the API does not match the default time.Time parse format and thus the unmarshal fails.

Is there any way to specify to the unmarshal function which date format to use in the time.Time parsing? I’d like to use properly defined types and using a string to hold a datetime field feels wrong.

Sample struct:

type Transaction struct {

    Id int64 `xml:"sequencenumber"`
    ReferenceNumber string `xml:"ourref"`
    Description string `xml:"description"`
    Type string `xml:"type"`
    CustomerID string `xml:"namecode"`
    DateEntered time.Time `xml:"enterdate"` //this is the field in question
    Gross float64 `xml:"gross"`
    Container TransactionDetailContainer `xml:"subfile"`

The date format returned is “yyyymmdd”.
