Marklogic 7 Problem with fn: format-dateTime

In MarkLogic 7.0-4, the function fn:format-dateTime

seems to return incorrect values ​​when fractional seconds start at 0.

The following query returns different results in MarkLogic 5.0-5 and 7.0-4

let $ currentUTCTime: = xs: dateTime ("2014-10-30T15: 23: 20.092563Z")

return n: Format-DateTime ($ currentUTCTime, "[Y0001] - [M01] - [D01] T [H01] :. [M01]: [S01] [F001]")

The correct result is 2014-10-30T15: 23: 20.092

MarkLogic 5.0-5 result - 2014-10-30T15: 23: 20.092

MarkLogic 7.0 - 4 result - 2014-10-30T15: 23: 20.930

This seems to be a bug. Does anyone know about this?
