You're right - I left the denouement implicit.

With this method (4a) UTC-SLS would not have the property listed in
section 3: "the time always equals UTC at full or half hours". I
think this is a valuable property; as the text following the 4a), 4b)
and 4c) options notes: "...would be reached at midnight, which is a
time commonly used to schedule events and deadlines."

I hope that makes sense.
