How can nxlog for windows be configured to send timestamp in high-precision forwarding format?

Similar to the RSYSLOG_ForwardFormat high-precision timestamps including year with timezone UTC offset information.

For example:

2017-08-22T18:36:28.568230+00:00

It is currently just being sent with ONLY Mon day hour:min:sec

Thanks!
