Any particular language's implementation of datetimes wouldn't preclude a common Thrift datetime data type, just like any language's other types don't preclude Thrift equivalents. Even with ms rather than us resolution, Windows and Linux still get along together.
Any language-specific Thrift library would just automatically encode/decode a datetime between Thrift and that language's datetime structure.
