> • In the BNF description, under Level 0, "baseTime" is defined as [hour ":" minute ":" second | "24:00:00"], however this conflicts with the definition of hour: "hour = zeroThru23".
It does not conflict.
> Agreed. 24:00:00 should not be allowed IMHO, as it represents midnight of the next day.
Conventionally, "24:00:00" represents the very end of the day. We chose to use this convention during the design process a few years ago.
> - Also in the BNF description, zone hour offset is currently defined as "zoneOffsetHour = oneThru13", but if I'm not mistaken, it should be "zoneOffsetHour = oneThru14".
The reason for our choice is that there is no time zone "behind 14:00".
