Hi Alain,

KEP 2 proposes to store in RFC3339, which is UTC based.

So storage still is UTC based.

But there are the outlined use cases which are explained in and linked to from 
the KEP which cannot be addressed purely on UTC base, because DST regimes 
introduce a dynamic offset against UTC that is changing in different directions 
at different times of the years in different regions.

Best regards,

Georg C. F. Greve
