Thank you for publishing a new version of the draft. Some feedback based on your new changes, the existing concerns raised prior not withstanding: * Nit: "... violations are greater then a second the loss..." should be "greater than a second" * You have not provided sufficient information for implementations on how to actually calculate time, only citing a single, out-of-publication reference. Besides Wikipedia and a humor page[0] stored on the Internet Archive, I have been unable to find a definitive source that describes MJD. Could you please in a future version describe in detail how an implementation take the time received and perform the necessary computation to something that could be applied to a system clock. * Would it not be more appropriate to break up the MIDP value so the MJD day and time offset from midnight be pout into separate keys? * Is there a specific reason why the document has now a mixture of "bit" and "byte"? For example, MIDP is 8 _bytes_, but RADI is 32 _bits_. It's reasonable to assume that a reader can distinguish, but having a mixture such as this could lead to errors in implementations due to reader error.
